VOZZ Voltage Transformer Metering/Protection
25 - 34.5 kV, outdoor, 150 - 200 kV BIL, 60 Hz
The VOZZ-15 and VOZZ-15G outdoor voltage transformers are used for high burden metering and relaying service on 25 kV systems. These units replace the Westinghouse PT-25 gum-filled potential transformers.
The VOZZ-20 and VOZZ-20G outdoor voltage transformers are designed for high burden application and are suitable for operating meters, relays, and supplying control power. These are a two bushing design for line-to-line application where the line-to-line voltage equals the primary rating of the transformer. The units can be connected line-to-ground/earth at reduced voltage.
