REPORT: The provisional estimate Rs. 2498315/- for repair and reconditioning of faulty 5MVA, 33/11KV Power Transformer of Make: GEC, Sl No: 214017/3, YOM:1971, which was failed at 3X5MVA, 33/11KV MUSS, Mangsuli in Kagwad Taluka in O&M Division, HESCOM, Athani on dated: 26.09.2025 at 33/11KV sub-station, Mangsuli.
The existing 5MVA,33/11KV Power transformer No.3, Make:GEC, Sl. No.: 214017/3, YOM:1971 at 33/11KV Sub-Station Mangsuli in O & M Division, HESCOM, Athani was experienced a trouble on dated 25.09.2025 around 11:45 am at the same 5MVA Power Transformer No-3 was tripped on OC and BH relays. After releasing gas from the BH relay and resetting the protection, a test charge was taken at 12:25 pm. However, the transformer tripped again immediately on OC and EF Relay. And the same was intimated to the BDM Staff HESCOM Chikkodi. The Asst. Executive Engineer(El), BDM Sub-Division, HESCOM Chikkodi along with staff had visited the station and observed carried out detailed testing of the transformer. The results revealed a shift of current towards neutral from the B-phase during the short circuit test, which is an anomaly. Furthermore, a large current was recorded in the LV MBT test on the neutral side, indicating a possible B-phase winding damage. During inspection, the top lid of the main transformer tank was opened to verify the firmness of the windings, which was found satisfactory. However, metallic granules were noticed inside the tank, and a burning smell of oil was observed, therefore, the above said troubled Power Transformer has to be shifted to the Power Transformer repair center for rectification and detail analysis of the quantum of damage internaly occured. Hence, The Assistant Executive Engineer(El) BDM Sub-Division HESCOM Chikkodi had declared that the above said 5MVA, 33/11KV Power Transformer was failed and submitted the detail report vide their office letter No CKD/AEE(El)/BDM/2025-26/125 Dated:26.09.2025 3780
This provisional estiamte is prepared as per the test results obtained and based on physical through inspection of Power Transformer at the site during test. However, actual quantity/ cost of estimate will be submitted after the detail inspection of all the internal parts of the subject power transformer by joint inspection committe constituted under the chairmanship of Honrable DT HESCOM Hubballi and members Chief Engineer O&M Zone, HESCOM, Belagavi, Executive Engineer (Ele) 33KV S&L Division, HESCOM, Belagavi and convener Executive Engineer (Ele) MRT Division, HESCOM, Belagavi.
Therefore, this estimate is prepared for repairs and reconditioning of faulty 5MVA, 33/11KV Power Transformer Make: GEC, Sl No: 214017/3, YOM:1971 which was failed on 26.09.2025 at 3X5MVA, 33/11KV MUSS, Mangsuli. The necessary spares and adequate labour charges are included in this estimate. Hence kindly requested to sanction the estimate at an early.

REPORT : This is an estimate amounting to Rs. 24,54,400/- (Rupees. Twenty four Lakhs Fifty four thousands Four hundred Only) has been prepared for repairing of faulty 33/11KV, 5MVA Power Transformer (Make: Techno Power Corporation bearing Sl No: TPC/33/11/5000 09/24) which was failed on 17.03.2023 at 33/11KV S/S Bidari of Jamkhandi taluka, O&M Division, HESCOM., Jamkhandi.
The subject power transformer is tested on site, on 17.03.2023 for its insulation resistance values, Further By using multimeter continuity checked. R phase HV-Ground, Y phase HV-Ground & B phase HV-Ground found continuity for different taps.(IR values of HV (R+Y+B) to EARTH is 2 MOhms) Drained out the oil upto inspection chamber, no finding observed and opened the top cover of OLTC no findings obserbed. For conducting the test for Open Circuit and Short Circuit while giving 3 ph power supply to HV side the “Y” phase fuse blown out immediately & unable to process the further transformer tests. From the above results. it is suspected that, HV side of transformer winding grounded, Hence recommended for thorough inspection at repairer bay. It can not be attended at site.
This estimate is prepared as per The detailed test report of this office Assistant Executive Engineer (El), BDM Sub-Division, Bagalkot vide letter No: No. BGK/BDM/AEE/AE/ 2022-23/417-22 Date: 18.03.2023. However actual quantity/cost estimate will be submitted after the inspection of the active parts of the power transformer by inspection commitee constituted by honarable DT HESCOM, CEE Belagavi,EEE MRT, EEE PMC and EEE Nodal Officer of juridiction. All the provisions for men and materials has been made in the estimate. Hence this estimate may kindly be sanctioned and repair work may please be entrusted to any of the reputed repairer, since this division do not have sufficient skilled manpower and equipments/infrastructure facility.

REPORT: The provisional estimate Rs. 2498315/- for repair and reconditioning of faulty 5MVA, 33/11KV Power Transformer of Make: GEC, Sl No: 214017/3, YOM:1971, which was failed at 3X5MVA, 33/11KV MUSS, Mangsuli in Kagwad Taluka in O&M Division, HESCOM, Athani on dated: 26.09.2025 at 33/11KV sub-station, Mangsuli.
The existing 5MVA,33/11KV Power transformer No.3, Make:GEC, Sl. No.: 214017/3, YOM:1971 at 33/11KV Sub-Station Mangsuli in O & M Division, HESCOM, Athani was experienced a trouble on dated 25.09.2025 around 11:45 am at the same 5MVA Power Transformer No-3 was tripped on OC and BH relays. After releasing gas from the BH relay and resetting the protection, a test charge was taken at 12:25 pm. However, the transformer tripped again immediately on OC and EF Relay. And the same was intimated to the BDM Staff HESCOM Chikkodi. The Asst. Executive Engineer(El), BDM Sub-Division, HESCOM Chikkodi along with staff had visited the station and observed carried out detailed testing of the transformer. The results revealed a shift of current towards neutral from the B-phase during the short circuit test, which is an anomaly. Furthermore, a large current was recorded in the LV MBT test on the neutral side, indicating a possible B-phase winding damage. During inspection, the top lid of the main transformer tank was opened to verify the firmness of the windings, which was found satisfactory. However, metallic granules were noticed inside the tank, and a burning smell of oil was observed, therefore, the above said troubled Power Transformer has to be shifted to the Power Transformer repair center for rectification and detail analysis of the quantum of damage internaly occured. Hence, The Assistant Executive Engineer(El) BDM Sub-Division HESCOM Chikkodi had declared that the above said 5MVA, 33/11KV Power Transformer was failed and submitted the detail report vide their office letter No CKD/AEE(El)/BDM/2025-26/125 Dated:26.09.2025 3780
This provisional estiamte is prepared as per the test results obtained and based on physical through inspection of Power Transformer at the site during test. However, actual quantity/ cost of estimate will be submitted after the detail inspection of all the internal parts of the subject power transformer by joint inspection committe constituted under the chairmanship of Honrable DT HESCOM Hubballi and members Chief Engineer O&M Zone, HESCOM, Belagavi, Executive Engineer (Ele) 33KV S&L Division, HESCOM, Belagavi and convener Executive Engineer (Ele) MRT Division, HESCOM, Belagavi.
Therefore, this estimate is prepared for repairs and reconditioning of faulty 5MVA, 33/11KV Power Transformer Make: GEC, Sl No: 214017/3, YOM:1971 which was failed on 26.09.2025 at 3X5MVA, 33/11KV MUSS, Mangsuli. The necessary spares and adequate labour charges are included in this estimate. Hence kindly requested to sanction the estimate at an early.

REPORT: The provisional estimate Rs. 2498315/- for repair and reconditioning of faulty 5MVA, 33/11KV Power Transformer of Make: GEC, Sl No: 214017/3, YOM:1971, which was failed at 3X5MVA, 33/11KV MUSS, Mangsuli in Kagwad Taluka in O&M Division, HESCOM, Athani on dated: 26.09.2025 at 33/11KV sub-station, Mangsuli.
The existing 5MVA,33/11KV Power transformer No.3, Make:GEC, Sl. No.: 214017/3, YOM:1971 at 33/11KV Sub-Station Mangsuli in O & M Division, HESCOM, Athani was experienced a trouble on dated 25.09.2025 around 11:45 am at the same 5MVA Power Transformer No-3 was tripped on OC and BH relays. After releasing gas from the BH relay and resetting the protection, a test charge was taken at 12:25 pm. However, the transformer tripped again immediately on OC and EF Relay. And the same was intimated to the BDM Staff HESCOM Chikkodi. The Asst. Executive Engineer(El), BDM Sub-Division, HESCOM Chikkodi along with staff had visited the station and observed carried out detailed testing of the transformer. The results revealed a shift of current towards neutral from the B-phase during the short circuit test, which is an anomaly. Furthermore, a large current was recorded in the LV MBT test on the neutral side, indicating a possible B-phase winding damage. During inspection, the top lid of the main transformer tank was opened to verify the firmness of the windings, which was found satisfactory. However, metallic granules were noticed inside the tank, and a burning smell of oil was observed, therefore, the above said troubled Power Transformer has to be shifted to the Power Transformer repair center for rectification and detail analysis of the quantum of damage internaly occured. Hence, The Assistant Executive Engineer(El) BDM Sub-Division HESCOM Chikkodi had declared that the above said 5MVA, 33/11KV Power Transformer was failed and submitted the detail report vide their office letter No CKD/AEE(El)/BDM/2025-26/125 Dated:26.09.2025 3780
This provisional estiamte is prepared as per the test results obtained and based on physical through inspection of Power Transformer at the site during test. However, actual quantity/ cost of estimate will be submitted after the detail inspection of all the internal parts of the subject power transformer by joint inspection committe constituted under the chairmanship of Honrable DT HESCOM Hubballi and members Chief Engineer O&M Zone, HESCOM, Belagavi, Executive Engineer (Ele) 33KV S&L Division, HESCOM, Belagavi and convener Executive Engineer (Ele) MRT Division, HESCOM, Belagavi.
Therefore, this estimate is prepared for repairs and reconditioning of faulty 5MVA, 33/11KV Power Transformer Make: GEC, Sl No: 214017/3, YOM:1971 which was failed on 26.09.2025 at 3X5MVA, 33/11KV MUSS, Mangsuli. The necessary spares and adequate labour charges are included in this estimate. Hence kindly requested to sanction the estimate at an early.

REPORT : This is an estimate amounting to Rs. 24,54,400/- (Rupees. Twenty four Lakhs Fifty four thousands Four hundred Only) has been prepared for repairing of faulty 33/11KV, 5MVA Power Transformer (Make: Techno Power Corporation bearing Sl No: TPC/33/11/5000 09/24) which was failed on 17.03.2023 at 33/11KV S/S Bidari of Jamkhandi taluka, O&M Division, HESCOM., Jamkhandi.
The subject power transformer is tested on site, on 17.03.2023 for its insulation resistance values, Further By using multimeter continuity checked. R phase HV-Ground, Y phase HV-Ground & B phase HV-Ground found continuity for different taps.(IR values of HV (R+Y+B) to EARTH is 2 MOhms) Drained out the oil upto inspection chamber, no finding observed and opened the top cover of OLTC no findings obserbed. For conducting the test for Open Circuit and Short Circuit while giving 3 ph power supply to HV side the “Y” phase fuse blown out immediately & unable to process the further transformer tests. From the above results. it is suspected that, HV side of transformer winding grounded, Hence recommended for thorough inspection at repairer bay. It can not be attended at site.
This estimate is prepared as per The detailed test report of this office Assistant Executive Engineer (El), BDM Sub-Division, Bagalkot vide letter No: No. BGK/BDM/AEE/AE/ 2022-23/417-22 Date: 18.03.2023. However actual quantity/cost estimate will be submitted after the inspection of the active parts of the power transformer by inspection commitee constituted by honarable DT HESCOM, CEE Belagavi,EEE MRT, EEE PMC and EEE Nodal Officer of juridiction. All the provisions for men and materials has been made in the estimate. Hence this estimate may kindly be sanctioned and repair work may please be entrusted to any of the reputed repairer, since this division do not have sufficient skilled manpower and equipments/infrastructure facility.

REPORT: The provisional estimate Rs. 2498315/- for repair and reconditioning of faulty 5MVA, 33/11KV Power Transformer of Make: GEC, Sl No: 214017/3, YOM:1971, which was failed at 3X5MVA, 33/11KV MUSS, Mangsuli in Kagwad Taluka in O&M Division, HESCOM, Athani on dated: 26.09.2025 at 33/11KV sub-station, Mangsuli.
The existing 5MVA,33/11KV Power transformer No.3, Make:GEC, Sl. No.: 214017/3, YOM:1971 at 33/11KV Sub-Station Mangsuli in O & M Division, HESCOM, Athani was experienced a trouble on dated 25.09.2025 around 11:45 am at the same 5MVA Power Transformer No-3 was tripped on OC and BH relays. After releasing gas from the BH relay and resetting the protection, a test charge was taken at 12:25 pm. However, the transformer tripped again immediately on OC and EF Relay. And the same was intimated to the BDM Staff HESCOM Chikkodi. The Asst. Executive Engineer(El), BDM Sub-Division, HESCOM Chikkodi along with staff had visited the station and observed carried out detailed testing of the transformer. The results revealed a shift of current towards neutral from the B-phase during the short circuit test, which is an anomaly. Furthermore, a large current was recorded in the LV MBT test on the neutral side, indicating a possible B-phase winding damage. During inspection, the top lid of the main transformer tank was opened to verify the firmness of the windings, which was found satisfactory. However, metallic granules were noticed inside the tank, and a burning smell of oil was observed, therefore, the above said troubled Power Transformer has to be shifted to the Power Transformer repair center for rectification and detail analysis of the quantum of damage internaly occured. Hence, The Assistant Executive Engineer(El) BDM Sub-Division HESCOM Chikkodi had declared that the above said 5MVA, 33/11KV Power Transformer was failed and submitted the detail report vide their office letter No CKD/AEE(El)/BDM/2025-26/125 Dated:26.09.2025 3780
This provisional estiamte is prepared as per the test results obtained and based on physical through inspection of Power Transformer at the site during test. However, actual quantity/ cost of estimate will be submitted after the detail inspection of all the internal parts of the subject power transformer by joint inspection committe constituted under the chairmanship of Honrable DT HESCOM Hubballi and members Chief Engineer O&M Zone, HESCOM, Belagavi, Executive Engineer (Ele) 33KV S&L Division, HESCOM, Belagavi and convener Executive Engineer (Ele) MRT Division, HESCOM, Belagavi.

REPORT : This is an estimate amounting to Rs. 24,54,400/- (Rupees. Twenty four Lakhs Fifty four thousands Four hundred Only) has been prepared for repairing of faulty 33/11KV, 5MVA Power Transformer (Make: Techno Power Corporation bearing Sl No: TPC/33/11/5000 09/24) which was failed on 17.03.2023 at 33/11KV S/S Bidari of Jamkhandi taluka, O&M Division, HESCOM., Jamkhandi.
The subject power transformer is tested on site, on 17.03.2023 for its insulation resistance values, Further By using multimeter continuity checked. R phase HV-Ground, Y phase HV-Ground & B phase HV-Ground found continuity for different taps.(IR values of HV (R+Y+B) to EARTH is 2 MOhms) Drained out the oil upto inspection chamber, no finding observed and opened the top cover of OLTC no findings obserbed. For conducting the test for Open Circuit and Short Circuit while giving 3 ph power supply to HV side the “Y” phase fuse blown out immediately & unable to process the further transformer tests. From the above results. it is suspected that, HV side of transformer winding grounded, Hence recommended for thorough inspection at repairer bay. It can not be attended at site.
This estimate is prepared as per The detailed test report of this office Assistant Executive Engineer (El), BDM Sub-Division, Bagalkot vide letter No: No. BGK/BDM/AEE/AE/ 2022-23/417-22 Date: 18.03.2023.

REPORT: The provisional estimate Rs. 2498315/- for repair and reconditioning of faulty 5MVA, 33/11KV Power Transformer of Make: GEC, Sl No: 214017/3, YOM:1971, which was failed at 3X5MVA, 33/11KV MUSS, Mangsuli in Kagwad Taluka in O&M Division, HESCOM, Athani on dated: 26.09.2025 at 33/11KV sub-station, Mangsuli.
The existing 5MVA,33/11KV Power transformer No.3, Make:GEC, Sl. No.: 214017/3, YOM:1971 at 33/11KV Sub-Station Mangsuli in O & M Division, HESCOM, Athani was experienced a trouble on dated 25.09.2025 around 11:45 am at the same 5MVA Power Transformer No-3 was tripped on OC and BH relays. After releasing gas from the BH relay and resetting the protection, a test charge was taken at 12:25 pm. However, the transformer tripped again immediately on OC and EF Relay. And the same was intimated to the BDM Staff HESCOM Chikkodi. The Asst. Executive Engineer(El), BDM Sub-Division, HESCOM Chikkodi along with staff had visited the station and observed carried out detailed testing of the transformer. The results revealed a shift of current towards neutral from the B-phase during the short circuit test, which is an anomaly. Furthermore, a large current was recorded in the LV MBT test on the neutral side, indicating a possible B-phase winding damage. During inspection, the top lid of the main transformer tank was opened to verify the firmness of the windings, which was found satisfactory. However, metallic granules were noticed inside the tank, and a burning smell of oil was observed, therefore, the above said troubled Power Transformer has to be shifted to the Power Transformer repair center for rectification and detail analysis of the quantum of damage internaly occured. Hence, The Assistant Executive Engineer(El) BDM Sub-Division HESCOM Chikkodi had declared that the above said 5MVA, 33/11KV Power Transformer was failed and submitted the detail report vide their office letter No CKD/AEE(El)/BDM/2025-26/125 Dated:26.09.2025 3780
This provisional estiamte is prepared as per the test results obtained and based on physical through inspection of Power Transformer at the site during test. However, actual quantity/ cost of estimate will be submitted after the detail inspection of all the internal parts of the subject power transformer by joint inspection committe constituted under the chairmanship of Honrable DT HESCOM Hubballi and members Chief Engineer O&M Zone, HESCOM, Belagavi, Executive Engineer (Ele) 33KV S&L Division, HESCOM, Belagavi and convener Executive Engineer (Ele) MRT Division, HESCOM, Belagavi.
Therefore, this estimate is prepared for repairs and reconditioning of faulty 5MVA, 33/11KV Power Transformer Make: GEC, Sl No: 214017/3, YOM:1971 which was failed on 26.09.2025 at 3X5MVA, 33/11KV MUSS, Mangsuli. The necessary spares and adequate labour charges are included in this estimate. Hence kindly requested to sanction the estimate at an early.
