REPLACEMENT OF EXISTING OLD HT PANEL INCL VCB BREAKER AT 33 ROORKEE ROAD UNDER GE UTILITY MEERUT CANTT

Supplying, installing, testing and commissioning of Indoor arc flash protected Draw-Out with roll on floor type Vacuum Circuit Breaker Panel , rated for 11kV, 1250Amp, 26.3kA/3-sec, comprising of Incomer with Line PT, & Riser confirming to IEC 62271-200, Internal Arc Classified IAC AFLR – 25kA for 3 sec, Accessibility Class LSC2B-PM Class, comprising of 1250Amp, continuous rated Copper busbars and droppers, 02 Nos. Rack-In-Rack-Out Handles, structure made from AluZinc/CRCA coated sheets steel of 2mm thickness to prevent corrosion and rusting. Panel Enclosure, VCB, Numerical relays, Online temp monitoring solution & Smart Local Monitoring HMI solution must be of same make OR Make recommended by OEM with provn performance for better life cycle optimization. Bottle should be vertical, horizontal type not acceptable. Each panel cable compartment must be equipped with integral making type earthswitch or Earthing truck is accepted. Each Panel cable compartment will have 3 nos wire less & battery less Temparature sensors one each for each phase & the data concentrators of the complete temparature solution must communicate to Smart Monitoring HMI over Modbus communication protocol. The complete panel incl. HT and LT chamber with FRLS wiring shall be manufactured by approved OEM at its own facility, and same will be verified via stage/final inspection. The Board shall consist of following panels:-

02 x Incomer Panel (each panel) comprising of :-

(i) 11kV, 1250Amp, 25 kAfor 3-sec, Draw-Out Vacuum Circuit Breaker as per IEC-62271-100 with roll on floor type Vacuum Circuit Breaker having 03 Nos. vacuum bottles of same make as of circuit breaker,copper busbar of cap 2000Amp, motorized spring charging mechanism (230VAC) with integral spring charging handle for manual charging, associated push-buttons, anti-pumping feature, and associated Shunt Trip/Close Coils (110VDC) along with 2 Nos Capacitor bank breaker (500KVAR).

(ii) Current Transformers 11kV, 600/1-1-1, Core1: Class 5P10, 5VA, Core2: Class 1, 5VA, Core3: Class PS-X - Set of 03 Nos. Insulation class E. The 'PS' core will be of suitable knee point voltage and ratio so as to succesfully implement Transformer Differential protection scheme for the upstream power transformer alongwith neutral CT combination schemde. (Makes - Pragati, ECS, Gemini, JSL)

(iii) Potential Transformers, Draw-out type for easy maintenance, 11kV/rt3:110V/rt3, 50VA, Cl.1 with associated gun-type HRC fuses and MCBs for HT/LT isolation - Set of 03 Nos. (Makes - Pragati, ECS, Gemini, JSL)

(iv) Main Protection Relay shall be numerical IED Relay confirming to IEC60255, having 04CT+04PT Inputs with microprocessor based protection scheme for tripping the breaker on various faults like (a) over-current & earth-fault in any of the three phases, (b) Synchronism and Energizing Check before breaker closing to prevent un-syncronized mixing of supplies (c) Over Voltage & Under Voltage protection (c) circuit-breaker-failure alarm, (d) interpanel tripping/blocking signals via GOOSE based peer-to-peer communication. The relay shall be communicable on IEC 61850 Edition 2.1 GOOSE platform over RJ-45, and fully integrated with the feeder, internally capturing feeder statuses incl. various status, Line-Current, Line-Voltage, Breaker On/Off/Spring.Chrgd, Trip Circuit Failure (from TCS relay), AC Supply Fail, PT Fuse failure relay, Local-Remote etc. and display locally on a built-in back-lit LCD screen with mimic as a Single-Line-Diagram with power & frequency measurements and suitably labelled status LEDs. Relay setting should be possible through inbuilt software or through addtional software supplied by the relay manufacturer.

(v) Metering Equipment including:- (a) 01 x Digital Voltmeter (Acc.Cl.0.5), 01 x Digital Ammeter (Acc.Cl.0.5), (b) 01no. Multi-Function-Meter (Acc.Cl.0.5) shall be provided with LCD display for measuring current, voltage, power, power-factor and energy-parameters, Total Harmonic Distortion and Max. Demand Indication, same shall be communicable on ModBus via RS485 port complete with all parameter

(vi) LED Indications :- (a) Breaker ON/OFF/TRIP/Spring-Charged, (b) R-Y-B, (c) DC Available LED with push-button (d) AC Supply Fail (e) Trip Circuit Healthy

(vii) 012-Window Annunciator with Hooter to indicate following alarms :- (a) OC Trip, (b) EF Trip (c) Trip Circuit Failure, (d) Inter-Tripping Fault, (e) Synchro-Check. (f) PT Fuse Failure (g) Over Voltage operated (h) Under Voltage operated The Annunciator will be complete with required Acknowledge/Test buttons as required

(viii) Control Equipment incl. :- (a) 01 x TNC Switch, (b) 01 x Local/Remote Switch, (c) 01 x Emergency Trip Push Button, (d) MCBs for AC (e) MCBs for DC (f) Heater Switch with Thermostat - 01no. (g) 3-pin socket with ON/OFF switch - 01no. (h) CFL Lamp with ON/OFF switch - 01no.
