The Gridview™ “all optical” sensor measures voltage and current by photon instead of electron. The sensor bodies do not contain conductive materials, which eliminates typical catastrophic failure methods of legacy instrument transformers. The HCEP insulator body construction provides superior arc tracking protection, as well as ozone and ultraviolet-resistive properties while maintaining physical strength. Signals from each sensor are connected via optical fiber connections to a modular “plug & play” m410 processing unit that is fully ruggedized and scalable. All calibration and performance settings are stored on the m410, which can be remotely accessed for programming and monitoring.
The Gridview™ medium voltage sensor contains no core and no coil. This sensor does not saturate or overheat in a high-current or overvoltage events as traditional instrument transformers do. The innovative benefit of the "all optical" design is that the Gridview™ medium voltage sensor allows for precise measurement of high-voltage and high-current events, not just survivability.
