Annual maintenance and repair of 11 KV electrical substations namely Substations 1,2,4,5,6 comprising of oil filled 11/.433 KV transformers: 2 nos. of 500KVA Voltamp make, 3 nos. of 1600KVA Kirloskar make, 2 nos of 1600 KVA Voltamp make, 2 nos of 1600 KVA Voltamp make,2 nos of 1000KVA Kirloskar make; Crompton Greaves & Kirloskar make HT panels and breakers with electronic relays, electronic voltmeter, ammeter, 22 nos of HT VCBs 800A of Crompton, Greaves / Kirloskar make, LT panel with busbars 55 nos of ACBs 800 to 2500A of L&T & ABB make, APFC panels of capacity 100 to 400 KVAR, 10 nos of Milestone / Associated make, 63A TPNs, Battery with battery charger, MCCBs,electronic voltmeter, ammeter, relays, APFC panels etc.,Deputing highly skilled trained person during working hours six days a week with following works in addition to as stipulated in detailed scope of work : 1. Testing of entire ACBs 800-2500A (55 nos) with OEM approved test kit. 2. Earthing check of all substations/panels/equipment (40 nos aprx.). 3. Testing of VCBs (25 nos) and relays (25 nos aprx) with kit. All switches and breakers are well connected to underground HT/LT cables laid in trenches with proper thimbles and the substaions are fully operational. NOTE: If activity at Sr. no. 1,2 and 3 are not undertaken, as indicated, then pro rata detection shall be made for less no. of testing undertaken according to actual work done. Similiaraly not deputing skilled staff shall attract detection on pro rata bases.
