Description

НТМИ-ADL-12kV is a three-phase oil-filled voltage transformer designed for voltage measurement, electricity metering and signal transmission to relay protection, automation and signalling equipment. It is used in 10 kV AC networks operating at 50 Hz with an isolated neutral.

The transformer reduces the primary voltage to the standard secondary value of 100 V and electrically insulates the measuring circuits from high voltage. The additional secondary winding is used to monitor network insulation and detect earth faults.

The magnetic core and windings are housed in a metal tank filled with transformer oil, which provides insulation and natural cooling of the active part. НТМИ-ADL-12kV is intended for indoor installation in switchgear at substations and industrial facilities.

The accuracy class, rated burden of the secondary windings and climatic version are selected according to the project requirements.
