LMZB-0.5 current transformer
The current transfonner is casting resin insulated and used indoors.It is used for relay protection in the electrical system with single - core cable up to rated frequency 50Hz or 60Hz and rated voltage lOkV.
¶þ¡¢ Type designation
The current transformer is busbar type. It has no primary winding. The single - core cable through it is as the pnmary winding.
ËÄ¡¢ Technical data
1.Because the cable protects the primary main insulation, so, the insulation characteristics of secondary winding are only examined. The secondary winding can be able to withstand the power frequency test voltage of 3kV to ground.
2.Rated primary and secondary current, ac-curacy classes, rated output see form
