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
- Optical fiber isolates the passive sensor at high voltage from grid edge electronics safely at ground potential
- 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 galvanic 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.
