The protecting device for DT hermetic transformers (without nitrogen cushion) tank
CEDASPE® OC is a protective device specially designed to detect potential gas generation inside the tank and is suitable for hermetically sealed transformers without nitrogen cushion. The CEDASPE® OC-MA/ML senses such faults, operating the alarm circuit. Air generated by these faults is captured and collected inside the gas accumulation chamber, where the movement of a float activates the magnetic switch. It is equipped with a large graduated window, allowing clear and easy inspection from outside. Designed according to EN 50216 Standard reference.
