Surge protective devices for energy networks

Energy networks

Comply with NF C 15-100, IEC 60364, UTE C 15-443, NF C 61-740 and IEC 61-643-1 standards
Concerns
Interference and discharges of atmospheric origin (lightning induced surges and electrostatic discharges) can create very strong electromagnetic radiation over large distances which can destroy all equipment connected to any nearby power lines. (Highly energetic discharges with long duration times, overvoltages larger than the component’s damage threshold voltage of electronic equipment, (...) read more

Overvoltage counter

Description
The overvoltage counter is intended for detecting and recording surge currents on any installations equipped with overvoltage protection systems (surge currents with atmospheric origins such as lightning strikes, interference produced on the mains ...). Designed for DIN foot systems, it is installed in serial on the path of the discharge current towards the earthing system, i.e on the earth conductor in serial in between the overvoltage protection device and earth system.

Coordination coils and filters

Coordination coils and filters - 230/400 V 
Comply with IEC 60364 and EN 138000 standards.
Description
Overvoltage protection of mains may need in the case of specific applications the arrangement in cascade of multiple levels of surge protective devices. It will then be essential to make these devices compatible together. The device compatibility is of critical interest when these have to be integrated in the same cabinet making the length of the cables interconnecting consecutive (...) read more
