Voltage Transformer ZNGA-110

The ZNGA-110 series anti-resonance voltage transformers are designed for transmitting measurement signals to metering, measuring, protection, and automation devices in 110 kV three-phase AC networks with a grounded neutral, operating at 50 Hz. These transformers feature three secondary windings: one for metering and measuring instruments, and an additional winding for network insulation monitoring. The terminal box is integrated into the tank with an IP-5X protection cover.

Additionally, the transformers are equipped with IEC 61850 compliant digital converters for GOOSE message transmission via fiber optic channels.
