The world's first thermal imaging relay was presented in Russia

The Research and Production Enterprise (NPP) Microprocessor Technologies has presented the world's first thermal imaging relay Cactus.

This relay solves the problem of overheating of contact joints of electrical equipment, which causes two thirds of all accidents at 0.4-10 kV substations. To do this, Cactus continuously monitors electrical equipment for overheating.

The sensitive element of the relay is a thermal imaging matrix. It is what makes it possible to monitor the temperature of a rectangular section of the plane, as well as automatically detect unacceptable overheating of the contact connections.

This method, in contrast to point devices, allows a larger area to be monitored.

In addition, the relay has an integrated ambient temperature sensor. Therefore the equipment is able to selectively distinguish overheating of the contact connections from a general increase in temperature in the monitored area.

Thanks to two digital outputs with redundant contacts the device integrates into local and central alarm circuits and cooling device control circuits.

Another function of Cactus is to provide immediate alarm cause analysis.
