Surge protection
Overvoltages can damage the secondary systems (secondary equipment). Lightning surge voltages can be coupled in via current or voltage transformers. Surge protective devices therefore increase the reliability and availability of the system. Therefore, we recommend using type 1+2 surge protective devices of the SEC product family.

Potential distribution

A reliable, stable auxiliary power supply is essential for the uninterrupted operation of substations. A high-performance surge protection system supports this goal by safely discharging transient overvoltages. In the control cabinet, innovative solutions for AC and DC potential distribution reduce the amount of space required as well as the installation time. Redundant solutions or batteries supplement the DC power supply when needed, thus safeguarding the 24 V supply even in critical situations. Function-based device circuit breakers reduce negative effects on the overall system in the event of a short circuit.
