Description

Description
LXK-80, 100,120 zero-sequence current transformer at 35kv and below. AC 50Hz line for the power system as well as the high voltage three-phase alternator, the motor's zero sequence over-current protection, and applies only to indoor. The outer diameter of the output cable is not greater than 120mm.

Characteristic of structure
Ths type of transtormer s divided nto two haves. Into a half crcle type cast resin, and then camping hoop conection. Installation can be mounted transtormer  divided into two halves. Then merged into one, very easy to install.

Applications
1.Ground Fault Protection
2.Leakage Current Monitoring Systems
3.Switchgear & Distribution Panels
4.Industrial Electrical Safety Systems
5.Retrofit Projects

Technical Data
The zero sequence curentransformer for the cable tpe, it s only necessary to examine the insulating properties of the secondary coil secondary coil can with stand the power requency withstand voltage 3KV.
