Wideband Optical Voltage Sensors
Passive optical sensors with all-dielectric fiber connection
NuGrid advanced optical sensors can improve grid reliability and resiliency. NuGrid focuses on leveraging optical sensing technology for measuring and monitoring faster phenomena across the grid safely and confidently. Two variants are available: a novel optical sensor for direct measurement of voltage for distribution applications, and an open voltage sensor (has no ground connection) for deployment at any voltage on the transmission or distribution system. NuGrid sensors sample at 1 million samples per second, providing bandwidth in excess of 100 kHz to see fast events including higher harmonics, switching and lightning transients, and traveling waves. The sensors also provide standard synchrophasor and IEC 61850-9-2 sampled-value outputs to support mainstream applications.
