Dielectric oil is essential for keeping certain underground, high voltage cables cool to carry electricity at an efficient level. If leaked into the ground, the oil can contaminate soils and groundwater causing costly cleanups. Leaking oil must also be added to the closed loop systems so that the temperature of the cables can be maintained. EnTech®’s Infrared – Energy Pattern Analysis (IR-EPA) leak detection system can help you regularly monitor your dielectric oil system for leaks so that they can be repaired before a costly failure.
