In nuclear power projects, safety margins are extremely tight. Any misoperation during commissioning, testing, or maintenance can have severe consequences. To ensure reliable testing and isolation of protection circuits, relay testblocks are always required at the front end of protection devices.

They enable:

Safe circuit isolation without dismantling wiring.
Accurate testing and calibration of protection devices.
Controlled switching under stringent nuclear safety protocols.

Customer Challenges

High reliability demand: Nuclear projects cannot tolerate equipment failures.
Complex electromagnetic environment: Strong interference risks require EMC-hardened components.
Strict standards: Test equipment must comply with international nuclear safety and reliability requirements.
