The current transformer TOLU-10-3, which you can order in our catalog, is used in switchgears.
It is manufactured in the climatic version "U", which means it is suitable for use in temperate climates.
It can be placed in any position outside and inside buildings (location category 1.2).The principle of operation is to convert the high voltage of the mains current to the parameters acceptable for taking measurements. The output of the transformer can be connected to measuring equipment, automation, and control devices. It also protects secondary circuits from high voltage.
The durability and quality of operation are ensured by the secondary winding core made of an innovative material. A nanocrystalline alloy is used for this purpose. This material does not experience magnetization under the influence of passing currents.
Thus, the output current parameters are not distorted, and the device itself retains its original metrological properties for a long time (50 years).
