The NGFS Electric Field Sensor is an easy-to-install floating sensor with passive optics near line potential delivering high bandwidth and exceptional frequency response. Ideal for observing harmonics and fast phenomena, the NGFS can be used as temporary investigative tool or installed permanently in conjunction with a voltage transformer as a high-bandwidth measurement solution. The NGFS is designed for safety, with complete optical isolation between the primary sensor and all secondary equipment. Ideal for travelling wave fault location, NuGrid NGFS sensors have been installed on high-voltage transmission networks, successfully locating hundreds of faults with speed and precision. NuGrid sensors offer a transformative approach to grid monitoring — delivering high-bandwidth visibility, operational efficiency, and asset intelligence at a fraction of the cost of traditional systems. Ease of deployment and low installed cost allow a small sensor installation to trial benefits in a small section of the grid.
