BRR - Bladder Rupture Relays

BRR – Bladder Rupture Relays combined with Pronal STP flexible separators are intelligent systems able to detect any liquid that is unusually present in the protective liquid storage bladder (oil in case of leakage or a connection / condensation defect linked to a dryer issue).

It’s composed an optical sensor installed in the bladder through the flange during assembly or a maintenance operation, and a connection unit that connects the sensor to the external control relay installed in the transformer’s electric switchboard. Equipped with two LEDs, the latter allows full-time visual monitoring. The red LED indicates an anomaly while the other is green in normal situations.
