On the basis of the original LFZJ1-10 current transformer, LFZJ1-10Q has added an umbrella shaped structure on the outer surface, thereby increasing the creepage on the outer surface
Distance, suitable for lightly polluted areas.

The LFZJ1 series current transformers are suitable for measuring current and electrical energy, as well as relay protection, in power systems with a rated voltage of 10KV and below at 50Hz.
