Current Transformer
Current position: Home > Current Transformer
Indirect Connection Type AC
1. Big AC Current Transformer is extensively used for indirect measurement as a current sensing part.
2. It requires big measurement range with high accuracy and small phase shift, and good insulation ability .
3. Comparing with the type inside meters, it has bigger hole to cross electricity cables and has housing, so the cost is relatively higher.
