Description
These series of potential transformer are single phase and full enclosed of casting resin. They are used for measuring electric energy, voltage control and relay protection in the electric non-useful-ground neutral system up to rated frequency 50Hz or 60Hz and rated voltage 12kV. The transformers can be executed according to the standards IEC60044-2 and GB1207-2006.
Model
Structure feature
The types of potential transformers have much merit, such as: electric arc resistance, ultraviolet ray and aging resistance, long creepage distance, little partial discharge and large caliber of resistance to over-voltage. The primaries of the products are protected with fused. The fused is installed inside the transformer. The fusible cutout’s fused current can match the transformers short-circuit force.
