JEDZ8-12ZJCQ Electronic Voltage Transformer

Short Description:

The AC electronic voltage transformers are applied to gas-insulated box-type switches with rated frequency of 50Hz and rated voltage of 10kV. It can output high-precision phase voltage measurement and zero sequence voltage measurement signals used by measurement and control devices. This product realizes primary and secondary integration with switch bodies including ring main unit(RMU) and ZW20, and other equipment such as FTU as well as DTU, with features of small size, light weight, excellent performance, reliable operation, easy installation and so on.
