Description

ТЗЛУ-ADL-70 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.

The transformers are manufactured in sizes 70, 100 and 205, with different transformation ratios to meet customer requirements.

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