Manufacture and supply of 500 KVA Automatic Voltage Regulator to supply constant Voltage to Panel board at Bishunpur Pump Canal of Minor Lift Canal Division Jaunpur

Providing and fixing of 500 KVA free standing floor mounting outdoor type, copper bounded servo controlled voltage stabiliser (SCVS) naturally oil cooled, (including first filling of oil) suitable for voltage range of input phase voltage (184-276 volt i.e. 230 volt with 20% fluctuations) the output phase voltage should be maintained at 230 volt 1%, with a speed of correction not less than 7-8V/sec. phase to neutral voltage. The SCVS shall have an output voltage setting of 400 volts to 440 volts and shall be supplied with Digital voltmeter & Ammeter with selector switch to read input/output voltages & Currents, Auto/manual control selector switch, sensitivity control LED indication lamps within fuses & controls, and protection against OVER/UNDER voltages, OVERLOAD, Single phasing & protection for sensing elements. SCVS shall have all accessories like cable end boxes, earthing terminals oil gauge silica gel breather, earthing terminal and complete as required. The SCVS shall conform to IS 9815 (with latest amendments) The AVR shall be suitable for unbalanced loads and unbalanced input voltage with individual correction in all three phases. The AVR shall be provided with the following protection like Overload, Short Circuit, Earth fault, Over voltage, Under voltage, Single Phase Prevention, High Temperature Spike and surge CONTROL AND INDICATION The following alarm and annunciation shall be provided Alarm 1 Low / High Voltage (out of input range) 2 Single Phase Prevention Alarm 3 High Temperature Alarm Indication LED Indications for Input Voltage ‘High’ /’ Low’ DEGREE OF PROTECTION The degree of protection for the enclosure shall be IP55 as it is an outdoor installation. COOLING METHOD Cooling method shall be Natural / Oil cooled TESTS All routine tests as per standards shall be conducted, for proper functioning of the equipment in presence of Departmental representative, complete in all respect. The Contractor must to do all test on load after Installation.
