Design, fabrication, installation, testing and commissioning of one no. LT control panel for 100hp HC pump at T/W no. 1 (Samba Town) The panel should be equipped with following components / features: - The panel should be fitted with 250 Amps MCCB and a set of RYB indicators at incoming side. Star delta starter. - The panel should be fitted with starter comprising of 2 no. air brake contractors, 1 No. 185 Amps for main and 1 no. 185 Amps for delta supply and 1 no. 95 Amps for star operation, 1 no. timer for changing over the supply of motor from star to delta, 2 Nos. push buttons for start and stop operation of motor. 1 No. MCB 6 Amps. for the protection of internal control wiring. A neat and clean internal control wiring should be made with flexible, copper cables to complete the star delta circuit of outgoing supply. Panel should be equipped with following devices and relays: a) Thermal Overload Relay – MN12 (L&T) b) Motor protection Relay: (MPD 192) c) Voltage Protection Relay: (GIC/Multispan) d) Single Phase Prevention Relay: (GIC) e) Star-Delta Timer Protection devices: - The panel should be equipped with relay which should be able to protect the motor from voltage and current related faults. Voltage related faults: - Single phasing, under voltage, over-voltage, unbalanced voltage. Current Related faults: - Over current / load, dry running, unbalanced current / load, earth leakage, short circuiting.
