Dismantling of old u/s & Supply, installation, commissioning & testing of) Vector Group YNyn0, ON-load Tap motion generator anticlockwise and clockwise on HV side to vary secondary voltage from (+) 5% TO (-) 15% in steps of 1.25%, HV Digital MICROPROCESSOR CARD along with upgrading the existing RTCC panel including replacement of existing manual Relay with new AVR Relay (ISO 9001:2015 CERTIFIED ) , having following specification :-The RTCC shall be upgraded such that it will maintain electrical properties, even under severe overload, under/over voltage and under/over frequency conditions. Input correction range shall be -30% to +20% of nominal input voltage. Upon turn on or restart, the output of the 132/11 kV TFR shall not exceed the specified output regulation limits. if the input voltage or frequency exceeds programmable minimum or maximum set points for a programmable time period (factory set for 10 seconds),When electrical parameters are back within acceptable limits for a programmable time period (factory set for 60 seconds), the output voltage is outside of acceptable programmed limits, the RTCC must give output command to electronically operate connected 132 KV Transformer.. Response Time: RTCC Line Voltage Regulation and Correction Time: Output regulation shall be +5%, -6%, given an input voltage variation of -30% to +30% for nominal, when within +/-5% of the nominal frequency. Load Regulation: No load to full load regulation shall be 3% typical under linear loading. Note: The existing RTCC shall be adjusted so that the combination of line voltage regulation and linear load regulation results in a maximum output voltage variation of +7% to -8% from nominal, when within +/-5% of the nominal frequency. Operating Frequency: The existing RTCC shall be capable of operating at +10% to -15% of the nominal frequency, 50Hz or 60Hz, with programmable high and low limits to alarm and electronically shut down the SF6 Breaker. Limits shall be set to +/-2Hz from nominal and electronic shutdown shall occur if limits are exceeded for 10 seconds. Once back within limits for a programmable time period of 60 seconds, the SF6 Breaker shall automatically restart. Over Voltage/Under Voltage Protection: against UV/OV . An aux. relay is energized to operate an hooter. The UV and OV state is shown on the LCD. You can also set the AVR to get an SMS on your mobile phone in case of OV/UV. The affect in change in voltage takes place only after the time delay (TD) has elapsed as set by the user. In other words, the relay will send command to the motor only after the time delay has elapsed. This is required to avoid the motor start/stop on frequent voltage fluctuations. This delay time can be set from 5 to 125 seconds. Contd/- to serial item no.6.01 of BoQ

Continuted Serial Item No. 6.00 This refers to the drop in line voltage from generating end to transformer primary. The LDC helps the AVR to compensate this drop. The feature is added on request on charge-able basis. In case auxiliary supply to AVR fails (from PT), the AF relay gets activated. You can also set the AVR to get an SMS on your mobile phone in case of auxiliary supply failure. If the OLTC/AVR malfunctions because of any reason for certain preset time (say 10 minutes) then the CF relay will get energised and activated. An alarm can be connected with this relay contacts. Once the controls resume the normal functions, the relay gets de-energized putting the alarm off. All this can be seen on the LCD. You can also set the AVR to get an SMS on your mobile phone in case of control failure of the OLTC AVR. This feature is used to indicate the tap position. The tap position is displayed on the LCD. You can get tap position on your mobile phone also (on request). Card can be monitored and control through a wireless SCADA application from anywhere in the world. You can monitor the complete parameters of a transformer like electrical parameters, winding temperature (sensor required), oil temperature (sensor required), oil level (sensor required), buclotz relay status. oil leakage (sensor required). You can connect 4 X analog sensors (4 - 20 mA OR 0 - 5 volts) to record and monitor the health of the HT transformer. You can connect 4 x digital sensor (pulse/counter) to check the status of transformer Buchholz’s relay, transformers breaker etc.,. You can connect winding temperature sensor, oil temperature sensor, oil level sensor at the analog inputs. Data can be monitored on LCD display of the OLTC AVR. If the AVR is GPRS enabled then you can also monitor the live data on SCADA application. In case a transformer if getting overloaded, you can get an instant alert on 5 mobile numbers so as to take immediate action. Optional feature can also be provided to start an alarm or switch off the breaker and hence the transformer to save it from over-heating, ONLY Original OEM is entitled for work . Contractor has to ensure it.Necessary test certificates & Latest Purchase Vouchers to be scrutnised / approved by Engg-in-Charge & GE first before execution at site . Any Defect occurring during this period due to bad workmanship of material, manufacturing defect shall be rectified or replaced free of cost. The contractor shall furnish written gaurantee on letter head for above mentioned to the GE immidiately after completion of work. Contractor has to ensure Post Audit of work, without that completion will not be issued.
