ACTAS - Advanced Circuit Breaker Test and Analysing Systems

Breakers are found at the key points of electrical energy transmission and distribution systems.

The relaibility of these breakers has a direct effect on the safety and efficiency of electrical supply networks.

They are designed to function perfectly even if they are subjected to influences such as dirt and fluctuations, high humidity and temperature, or if they have not been operated for some time.

Should a short circuit occur, circuit breakers must interrupt extremely high fault currents with immediate affect.

The overall reliability of freshly installed breakers depends on their construction, quality of manufacturing, and the type and scope of final factory inspections and tests.

Automatic test systems provide precise information as to the state of the switching chamber and drive unit throughout the entire operational life of a breaker without requiring these to be opened.

The sheer number of parameters to be calculated, the wide variety of different breakers in use and the harsh environmental conditions encountered during on-site tests make extremely high demands on the test technology involved.
