detailed introduce：LZZB8-20 current transformer
- Project description：
一、Description
The current transformer of the type LZZB8.- 20 is casting resin, full enclosed and post type product. Itis used for metering electric energy and current, relay protection in the electrical system of rated frequency 50Hz or 60Hz and rated voltage 20kV. The transformers can be executed according to the standards IEC60044 -l and GB1208.二、Type description
三、Construction
This type of current transformer is fully enclosed and post moisture proof and antipollution. It is small and light. It can be installed at any place and any direction. The primary winding of single ratio transformer is fixation type. The pnmary winding of double ratio one is series and parallel. See rig, when series, it is 100/5A; when parallel, it is 200/5A.
