Description

ТЗЛУ-ADL-125 zero-sequence current transformers are designed to monitor zero-sequence currents and transmit a signal to relay protection, automation and signalling devices.

The transformers are used in complete switchgear, single-sided service switchgear cubicles, complete transformer substations and other AC electrical installations.

The transformers are cast-resin indoor zero-sequence current transformers with epoxy compound insulation, designed for AC electrical networks operating at 50 or 60 Hz with a highest equipment voltage of 0,66 kV.

Transformation ratios are specified according to the customer’s requirements.

The transformers comply with DSTU EN IEC 61869-2, have climate category У3, and are designed for operation in enclosed electrical installations.
