GSK (F) - Interior and overhead current transformers with the opened core in the resin housing

The current transformers are made of soft magnetic, highly permeable cut wound cores. Each half of the core is uniformly wound for better detection of the magnetic field. Two plugs connect the two halves when mounted. Four socket-head cap screws with compression springs hold the two halves of the housing together, thus guaranteeing the correct pressure at the cut core surfaces.

The output terminals come equipped with M5 screws. Protection against accidental contact is provided by a transparent polycarbonate cap. The modular mould system of the GSK permits almost any combination of housing and window sizes. To guarantee the mechanical and electrical resistance of the transformers they are encapsulated in a cast-resin housing with polyurethane. The GSK split-core current transformers are equipped with two base plates as standard that allow them to be mounted in any position. They require no maintenance.

During the final inspection at ELEQ the current transformers are always subjected to a routine test in accordance with the relevant national and international standards

Caution: if current transformers are operated open-circuited on the secondary side, extremely high voltages can be generated with resultant damage to equipment and personnel!
