Product Overview

The current transformer of the type LMZJ1-0.5 is casting unsaturated resin busbar type product.It is used for metering current and electric energy,relay protection in the electrical system o rated frequency 50Hz or 60Hz and rated voltage 0.5kV. The current transformer has the character of small volume,lightweight,superior insulation and so on. The transformer can be executed according to the standardslEC44-1:1996andGB1208-2006《Current transformer》.

Performance Index

▪ Rated insulation level: the secondary winding can withstand 3kV power frequency voltage to ground.
▪ Power factor of load: COSφ=0.8(lag)
▪ Rated secondary current:5A,1A
▪ Can manufacture 0.2s or 0.5S high precision current transformers for measurement.
