Control Relay Panels

A control & relay panel is designed to provide to control the associated line or transformer through outdoor switchgear at various 11KV and 33KV zonal substations. The control & Relay panels are complete in themselves with all main and auxiliary relays, annunciation relay, fuses, links, switches, wiring, labels, terminal blocks, earthing terminals, base frame, foundation bolts, illumination, cable glands etc. These panels are used for the control & monitoring of electrical equipments such as transformers, generators and circuit breakers. Indoor Control panel for Outdoor VCB includes IDMT Numerical relay, Master Trip Relay, Trip circuit Supervision Relay, Indications & meters etc. These control & Relays panels are available in various combinations as single circuit or multi-circuit depending upon the customer requirements.

• Feeder Panels: A feeder panel scheme consists of feeder circuits for either 11KV or 33KV switchgear. These panels are available in the form of over current & Earth fault relay having two O/C and one E/F element. Single point annunciator is provided for generating the alarm during fault condition as well as annunciation to indicate the type of faults and breaker status indication.
• Transformer Panels: A transformer panel scheme consists of transformer  circuits for either 11KV or 33KV switchgear. These panels are available in the form of over current & Earth fault relay having two O/C and one E/F element for 11kV and three O/C elements for 33kV rating. Single point annunciator is provided for generating the alarm during various types of transformer fault condition as well as annunciation to indicate the type of faults and breaker status indication.

•   One Transformer & One Feeder Panels: A multi circuit one transformer & one feeder panel is a combination of a transformer & a feeder circuit in a single panel built for either 11KV or 33KV Switchgear.The transformer circuit shall be same as in single circuit transformer panel. Similarly the feeder circuit shall be same as in single circuit feeder panel.
• Two Feeder Panels: A Multicircuit two feeder panel consists of 2 feeder circuits in a single panel. These panels are exact replica of multi circuit one transformer & one feeder panel in that there shall be additional feeder circuit in place of transformer circuit.
• Two transformer Panels: A Two transformer control & relay panel consists of two transformer circuits in a single panel. These panels are exact replica of multi circuit one transformer & one feeder panel in that there shall be additional transformer circuit in place of feeder circuit.
