Premium Flag Relays for Transformer Protection and Control Systems
Flag Relays are essential electrical protection devices used to provide a clear visual indication when a protection relay or electrical control circuit has operated. Commonly installed in transformer protection panels, substations, switchgear, and industrial control systems, Flag Relays help maintenance personnel quickly identify fault conditions, enabling faster troubleshooting and minimizing equipment downtime.
At Star Group of Companies Caribbean, we supply premium-quality Flag Relays in Trinidad and Tobago, engineered for reliable operation, fast response, and long service life. These relays feature a mechanical flag indicator that remains visible after activation until manually reset, allowing operators to accurately identify the protection circuit that initiated the trip or alarm.
Designed to comply with international electrical standards, our Flag Relays are suitable for power transformers, distribution transformers, substations, utility networks, industrial facilities, and power generation systems throughout Trinidad and Tobago and the wider Caribbean.
