Current transformers 6(10)-35 kV

Current transformers series LZZB (production: HEAG) used in power plants in the distribution of high voltage circuits relaying, metering and billing of electricity.

The principle of operation is based on an electromagnetic transformer converting the measured current flowing through the primary winding, a current having a substantially smaller value proportional acceptable standard for measuring instrumentation.

Instruments series LZZB - single phase cast resin transformers reference type, which is made of epoxy resin (for indoor use), and with a shell made ​​of silicone rubber (for outdoor use).

Modifications for indoor installation (LZZBJ9-12, LZZBJ12-12, LZZB (J) 9-35, LZZB (J) 7-35) and outdoor (LZZBJ71-12W, LZZBW8-35) different nominal (most effective) voltage design mounting at the installation location, the number of windings, dimensions and weight.
