Detailed Product Description

High Voltage Potentail Transformer  of the types are casting resin insulated and semi-enclosed products. They are used for metering electric energy, voltage control and relay protection in the electric system up to rated frequency 50Hz or 60Hz and rated voltage 3KV, 6KV and 10KV.

Construction

The voltage transformer is combination of a product with three phases and three poles and a product with single phase and double poles. The terminal N of the three phase and three poles product is not earthed and series with another terminal N of the single-phase product. The terminal O must be earthen when operating. When the system can working normally and not is breakage.

Technical data

1. the voltage transformers are in accordance with GB1207-1997Voltage transformerstandards; 2. power factor of load: COSΦ=0.8(lagging);

3. surface creepage distance: the product accords with the request of II class;
