Voltage transformers cast type ZNOL, ZNOLP, 6-10kV

Voltage transformers ZNOL, ZNOLP type are single-phase, cast, three-winding, intended for the needs of the power industry. Transformers are installed in complete switchgear and conductors and are used to transmit the measurement information signal to measurement, protection, automation, alarm and control devices in 50 Hz AC electrical circuits.

Transformers ZNOL, ZNOLP type operate for a long time at increased voltage (more than 3Unom), which occurred on any of the three phases due to ferroresonance phenomena in the network, and also have a weak dependence of errors on the load power.
