I.             Description
This current transformer is indoor busbar-type, it's used for current power measurement in A.C. power line with rated voltage 0.66kV and below, rated frequency 50Hz or 60Hz. It cast the current ratio on the surface of this CT to prevent the electricity theft due to changing the through core turns. Furthermore, the secondary outlet is housed with sealed covert and fixed screw with lead sealed holes, after sealing, it will prevent the electricity theft due to change of secondary connection.
