Designing, Fabrication, Installation, Testing and Commissioning of 100 KVA Manual Voltage Stabilizer along with allied works at P/S Toph Sherkhania under District Capex Budget 2026-27.

Providing, installation, testing and commissioning of 100 KVA, 3 phase, copper wound, oil cooled manual voltage stabilizers, with operating voltage of 320-480 Volts and operating frequency of 47-53 Hz at pumping station Toph Sherkhania. The stabilizer should be provided with digital voltage and current display for independent phases with selector switches along with RYB phase indicators. The stabilizers shall be incorporated with 250 Amp. MCCB to disconnect outgoing power supply from voltage stabilizer when need arises. The stabilizer shall also incorporated with change over switch capable of running in three modes viz. bye pass, power supply through voltage stabilizer and cut off mode. The stabilizer should be mounted on unidirectional wheels. The job includes shifting of stabilizer to site of installation by means of mechanical transport, skilled labour and crane. The job include making of all the incoming and outgoing connections of voltage stabilizers after proper thimbling of cables ends with the help of crimping tool. Testing of stabilizers on full load. The Job also includes providing laying and fitting of single core 120 Sq.mm 3.5 core Aluminum Armoured cable 10 mtrs. in length approx. from voltage stabilizer to panel alongwith proper insulation and thimbling. Complete job including cost of equipment material, transformer oil, carriage charges, hire charges of mechanical transport and crane. Characteristic features: 1. Continuous duty performance over ambient temperature 2°c to 55°c. 2. Low internal impedance. 3. Negligible wave distortion during operation and stopping. 4. Stable and effective under system power factor and frequency fluctuation as well as on over load with connected machinery. 5. Accommodate the effects of higher starting current and should be able to recover from shock. 6. The total capacity oil tank should be indicated. 7. The stabilizer shall have a suitable breather transformer oil level indicator and leak proof de -sludging/drain cock for transformer oil. The job also include providing, installation, testing and commissioning of MCCB-150 ampere (4 pole) for L.T. Control Panel of units No. 1 and 2 & providing and fitting of MCCB/Switch Fuse Unit of 250 Ampere (4 pole) alongwith 50 Sq.mm Aluminum Cable (3 core) of 15 mtr. length alongwith allied electromechanical works, Complete Job
