Model JVP-1 Outdoor Voltage Transformer
Outdoor voltage transformer for metering, protective relaying, and control power; rated 750 VA.
Our JVP-1 provides reliable outdoor voltage transformer performance for metering, protective relaying, and control power.
Overview
The Model JVP-1 Outdoor Voltage Transformer is engineered for outdoor service in utility, industrial, and commercial electrical distribution installations, targeting metering, protective relaying, and control power. Designed for indoor service; suitable for operating meters, instruments, relays, and control devices. Thermal Rating 55°C Rise Above 30 °C Ambient
Constructed with precision-wound cores and robust insulation, the JVP-1 maintains rated accuracy through repeated thermal cycling, mechanical vibration, and environmental exposure typical of outdoor installations. Key ratings: 750 VA. Design conforms to IEEE C57.13 (where applicable) for instrument-transformer accuracy and dielectric testing.
Typical deployments include substation switchgear, generator and transformer protection, revenue metering, feeder and motor protection, and control-room instrumentation. Refer to the attached data sheet for complete ratio, burden, accuracy class, and dimensional details; contact our engineering team for custom ratings, extended range, or non-standard configurations.
