GSA (F) - Интерьер и воздушные трансформаторы тока в жилье смолы

The current transformers are made of toroidal, soft magnetic, highly permeable tape-wound cores. The cores being uniformly wound with copper wire. For larger current strengths the cores come with stabilising windings to counteract the influence of external fields. Depending on the customer requirements each housing can accommodate up to five cores.

The output terminals are equiped with M5 screws. Protection against accidental contact is provided by a transparent polycarbonate cap. The modular mould system of the GSA 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 GSA ring-type current transformers are equiped with two base plates as standard that allow them to be mounted in any position. They require no maintenance. In addition, for the outdoor transformers the output terminals are covered with an aluminium terminal box protected to IP54. Wire entry is via a PG16 threaded conduit in the terminal box.

When the current transformers need to be installed in locations with heavy vibration (for example, generator terminal boxes) the secondary terminals and the two base plates are reinforced in the resine housing (GSAG).

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!
