NGFP Field Probe

Wide bandwidth and highly linear output for a range of applications

The NGFP electric and magnetic field probe is a highly flexible tool for adding visibility to voltage and current related phenomena at critical points on the grid.

With an all-dialectric design and fiber cable for isolation, it can be quickly and easily installed as a new measurement layer completely independent from existing instrument transformers, relays and other equipment.

NGFP Data Sheet

Unique, high-bandwidth optical electric field and/or magnetic field sensor

- Measure electric field, magnetic field or both
- 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
- Ideal for cable monitoring and fault location applications
- High resolution data recording
- Compact probe with accessories available for a range of voltages, or for indoor/outdoor installation
- Microsecond sampling faithfully reproduces harmonics and transient events

Portable and Flexible

- Valuable as a temporary investigative tool or installed permanently as a high-bandwidth measurement solution
- Variety of mounting options

Safe and Cost Effective

- Field probes are easily and quickly installed with a compact dielectric design
- Placement is often at ground potential with no outage
- Install indepedently of other instrumenation, cabling, relays and other equipment for fast deployment at scale

Performance

Bandwidth to accurately reproduce harmonics and transients.

All Optical

Non-conductive fiber-optic cabling completely isolates the sensor outputs from primary sensor near high voltage for maximum installation and user safety.

Analog & Digital

61850-9-2 digital out with high resolution data recording, PMU and low energy analog outputs.

Digital Recording

Local triggering and recording of time tagged high resolution waveforms.
