Model JVM-4C Indoor Voltage Transformer
Indoor voltage transformer for metering, protective relaying, and control power; rated 110 kV, 110 kV BIL, 500 VA.
Our JVM-4C provides reliable indoor voltage transformer performance for metering, protective relaying, and control power.
Overview
The Model JVM-4C Indoor Voltage Transformer is engineered for indoor 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. Regulatory Agency Approvals UL Recognized
Constructed with precision-wound cores and robust insulation, the JVM-4C maintains rated accuracy through repeated thermal cycling, mechanical vibration, and environmental exposure typical of indoor installations. Key ratings: 110 kV, 110 kV BIL, 500 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.
