NGVS Medium Voltage Sensor

Safe, wide-band voltage measurement

- Passive optical primary sensor with no electronics at line potential for long-term reliability and stability
- Non-conductive fiber-optic cabling completely isolates the sensor outputs from primary sensor at high voltage for maximum installation and user safety
- Class 0.5 accuracy with excellent frequency response. 100+ kHz bandwidth is standard.
- Versatile digital platform with merging unit output and available voltage synchrophasors
- On-board D/A converter gives analog output for ease of interface to legacy instrumentation system

Bandwidth to faithfully reproduce harmonics and transients, ideally suited for travelling wave fault location.

Passive optics at line potential with complete electrical isolation between instrumentation and high voltage environment.

Low energy analog output, as well as digital 61850-9-2 and synchrophasor outputs.

Local triggering and recording of time tagged high resolution waveforms.
