NGFS Electric Field Sensor

The NGFS Electric Field Sensor is an easy-to-install floating sensor with passive optics at line potential delivering high bandwidth and exceptional frequency response for observing harmonics and fast phenomena.

NGFS Data Sheet

Unique, high-bandwidth optical electric field sensor

- Passive optical primary sensor with no electronics at line potential for long-term reliability and stability
- 100+ kHz bandwidth
- Visibility for renewables integration at distribution and transmission voltages
- Optional analog output for ease of interface to legacy instrumentation systems

Safe and Cost Effective

- Typically installed in an hour or two with no need for an outage and no disruption to other measurement or protection equipment

Performance

Bandwidth to faithfully reproduce harmonics and transients.

All Optical

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

Analog & Digital

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

Digital Recording

Local triggering and recording of time tagged high resolution waveforms.
