Description

3-ЗНОЛП-ADL-12kV is a three-phase group of cast-resin voltage transformers designed for voltage measurement, electricity metering and signal transmission to relay protection, automation and control equipment. It is used in networks with a nominal voltage of 10 kV and a maximum operating voltage of 12 kV.

The group combines three single-phase earthed ЗНОЛП transformers with fuse protection devices. Cast insulation based on epoxy compound provides dielectric strength and insulates the secondary circuits from high voltage. The equipment is intended for indoor installation in switchgear at substations and industrial facilities.

The transformation ratio, accuracy classes and rated burdens of the secondary windings are specified according to the project requirements.
