Description of Panel:-Fabrication, installation, testing and commissioning of LT control panel cum star delta starter for operation of 180 HP Motor at CPS Muthi Village. The panel shall be steel sheet enclosed dust and vermin proof fabricated out of 14/16 SWG pressed and shaped CRCA sheet steel supported on MS angle of 75 mm ISMC of suitable size and provision for fixing it on the ground with the help of foundation bolts. Panel edges and door edges shall be reinforced against distortion. The panel should be sturdy enough for vibration free operation and should be equipped with suitable locking / sealing arrangements. The structure should be provided suitable entry and exit holes for incoming and outgoing cables. The panel should be given two coats of anti rust primer and two coats of powdered coated steel grey paint. The panel should be equipped with following components. Incoming Panel box: The incoming panel box should be fitted with an MCCB of 630 Ampere. Capacity having display with ON / OFF, trip indicating light, digital Multi function meter with communication port (RJ485), digital voltmeter, digital ammeter, control fuse etc. of approved make L&T,GE spectronics / Schneider/HPL/C&S. Star Delta starter: The panel should be fitted with a fully automatic star delta starter comprises air break contactor of 02 Nos. MNX-400 air break contactors of each for main and delta supply and 1 No. MNX-325 air break contractor for star operation,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, 3 Nos. indicators for status of starter i.e. running, tripped, by passed / in line of protection system.1No.MCB 2 Amps. for the protection of internal control wiring. Complete accessories of approved make L&T, GE spectronics / Schneider/HPL/C&S. Neat and clean internal control wiring should be made with flexible copper cables to complete the star delta circuit of outgoing supply. Protection devise: The panel should be fitted with protections devices like relay, CT/PT, timer, ROM of suitable rating having inbuilt display ON/OFF, control fuse, fault analyzer with capacity to protect motor by isolating the power supply of motor by de-energizing the starter / panel from following electromechanical faults which may otherwise damage the motor windings:- a. Voltage related fault:- Single phasing, under voltage, over voltage, unbalance voltage / reverse phasing. b. Current related fault:- Over current / load, dry running, unbalance current / load, earth leakage,short circuiting. c. Mechanical fault:- Locked rotor, broken shaft. d.
