Benefits of Control and Relay Panels
Complete Substation Protection: Protects your transformer, feeder, and bus from overcurrent, earth fault, short circuit, distance faults and differential faults. Prevents costly equipment damage.
Fast Fault Detection & Tripping: Integrated numerical relays from Siemens, ABB, Schneider trip the breaker in <40ms – minimizing outage time and saving your power transformer worth lakhs.
Centralized Control: Single panel to control ON/OFF, Tap Changer, Breaker status, and interlocking – no need to go to the switchyard.
Reduces Downtime by 70%: With fascia annunciation and fault recorder, your operator knows exactly which feeder tripped and why. Faster restoration.
Saves Space & Wiring Cost: Duplex design accommodates 2 feeders in one panel. Pre-wired, tested, and ready to install – cuts site wiring time by 50%.
Future Ready & Customizable: Built on your SLD. Any relay combination, any voltage 11kV to 400kV, simplex/duplex, with mimic. No standard model compulsion.
Ease of Maintenance: Front access, draw-out relay cases, 20% spare terminals and ferruled wiring makes troubleshooting and relay replacement easy.
Accurate Metering & Energy Auditing: Built-in digital meters, transducers and energy meters for precise load monitoring and energy audit.
