The GridView(TM) Medium Voltage & Current Sensor is a direct replacement for standard power transformers and current transformers. Because of the «all optical» sensor design, there are no conductive materials used for the measurement of both voltage and current. The insulator body is casted in hydrophobic cycloaliphatic epoxy (HCEP) using a state of the art injection molding process. HCEP construction provides superior arc track, ozone, and ultraviolet-resistive properties while maintaining physical strength. The hydrophobic surface properties of HCEP ensure highly reliable performance in wet or humid conditions. All calibration and performance settings are stored in the ruggedized modular electronics enclosure at the base of the optical cable. The m410 Modular Optical Sensor Processor provides a «highly accurate» as well as «low cost» precision solution for distribution grid monitoring and control.
