Control & Relay Panels
Control & Relay Panels
Protection, control, RTU and PLC panels for substations, generation, industrial plants and renewable interfaces — built around numerical relays with configurable software and engineered protection schemes.
Numerical relay protection
Multi-function numerical relays for over-current, earth-fault, differential, distance, busbar, transformer and generator protection. Each scheme is engineered against the customer protection philosophy — not a generic library — with settings, logic and reports verified before despatch.
Configurable software & logic
Relay and PLC logic configured for the specific scheme — interlocks, auto-changeover, load-shedding, breaker-fail and trip-circuit supervision — and pre-tested with simulated inputs in the panel-shop test bay.
Control desks & mosaic panels
Operator control desks with mosaic mimics, indication lamps, control switches, multi-function meters and HMIs. Engineered for operator ergonomics and integrated with substation automation where required.
- IEC 61850 ready IEDs
- Hardwired backup control
- Annunciation panels with audible & visual alarms
- Energy and disturbance recorders
RTU & PLC panels
RTU panels for SCADA interfacing and PLC panels for plant automation, with redundant power supplies, surge protection and segregated wireways for power, control and communication cables.
