36-52 kV N.S.V., Outdoor, 200-250 kV BIL
The Type 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 Types VOZZ-20, VOZZ-20G, VOZZ-25 and VOZZ-25G are outdoor voltage transformers 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.
