Digital voltmeter , 01no.Digital Ammeter along with suitable set of CTs and set of RYB phase indicators at incoming side including the suitable bus bars of appropriate size. The starter panel should comprise of 3-Pole Power Contactors of 185A rating (2No.s) (L&T(Lauritz Knudsen)/ Schneider / Havells/ABB/ Equivalent Reputed make), (1 No.)Power contactor 110 A rating (L&T(Lauritz Knudsen) /Schneider/ Havells/ABB/ equivalent reputed make), suitable for star delta starter for 100 HP motor, 1 No. timer for change over the supply of motor from star to delta, 2 Nos. push buttons for start and stop operation of motor,02 No. selector switches, 1 No. MCB of appropriate rating for the protection of internal control wiring, a neat and clean internal control wiring should be made with flexible copper cables/ bus bars to complete the star delta circuit of outgoing supply for pumping unit no.1 at LIS Jathana. The star delta starter should have the following protections of standard /reputed make to protect the motor from following electro-mechanical faults which may otherwise damage the motor windings: Voltage related faults :Single phasing, Reverse phasing, under voltage, over voltage, unbalance voltage. Current related faults: Over current / load, dry running, unbalance current / load, other faults: protection from earth fault. Moreover, thermal overload relay of suitable range should be fitted in the starter panel as an extra protection to the motor. The starter panel must display incoming voltage of all three phases, current of all three phases.
