Protection Relay Testing | BCJ Controls | Grid Protection

Our protection relay testing schemes are suited to solar protection relays, Though we can test any relay. Transformers, feeders, capacitors, generators. We can cover all of the protection requirements. This runs from simple overcurrent and earth fault relays, through to high-level differential and distance protection schemes.
