tender for maintenance of 2 no. new 33kv o/c and e/f relay alstom make maintenance of 2 no. new 33kv o/c and e/f relay alstom make at 132kv s/s tundla under etd, firozabad, 1 supply of over current earth fault relay alstom/siemens/abb/ziv make suitable for 33 kv feeder relay panel with following features. (a) having atleast 6 bi 7 bo with 1 alarm output(b)aux supply 110 v dc (c) having aux current 1a and voltage -110 v (d) having internal e/f & o/c and also time delayed e/f & o/c features. (e) communication interface rs-485 2 retrofitting/refitting of new relays by cutting ms sheet of relays size and mounting it with proper drilling and tighting with nut bolts , painting , the used ms sheet with same colours as panel dismantaling old defected/damaged relay by way of opening the terminal connection of old relays.with all connection checked through all circuit for proper functioning and check for dc inputs. 3 rewiring in relay panel with proper dressing , ferruling and termination in c&r panel . work should be done by skilled engineer. 4 work for commissioning and testing of new installed relays and all required test should be done related to related to relays as per testing standards of t&c team. testing of extracting data from relay,checking dr, checking for access from laptop and then final testing of relays for tripping check and proper functioning.testing instruments will be provided bydepartment & testing should be done by skilled engineer .
