Current Transformer BH-0.66-30-100-5.SDH.LN from JUCRO EleCTric
DescriPTion
The current transformer is used for measuring electric energy and current, relay protection in the electric systems up to rated frequency 50Hz or 60Hz and rated voltage 0.66kV.
Type description
Note:Type I (square circuit hole) capable of passing through either the cable or the purpose of monitoring.
Type II(horizontal square hole) capable of passing through 1-3 bus bar(s) is generally used for the purpose of monitoring.
Type III(vertical square hole) capable of passing through 1-3 bus bar(s) has the same characteristics of Type I and Type II, and is also intended to measure the electric energy of power supply system(Class0.2).It can still be used at larger secondary impedance and act as the zero-sequence current transformer.
Construction
The iron core is loop type. The secondary winding go uniformity around the core. There has hole for the busbar going through on the nip.
