LX series zero-sequence current transformer
is suitable for zero-sequence over-current protection and small-current
grounding line selection device in AC power system, distribution line, and
electrical equipment such as alternator and motor. The diameter of the cable is φ100mm～φ240mm.
The series of zero-sequence current
transformers are made of imported high-quality silicon steel sheets by special
process to form a toroidal core with high accuracy and accurate limiting
factor. The iron core and secondary winding are vacuum casted with high quality
epoxy resin. The plastic housing is moisture-proof, stable in performance and
maintenance-free. It is small in size, light in weight and small in space.
LXK series with splitable core type zero
sequence current transformer consists of two semi-rings, which can be installed
on the connected cable easily
