Type UOV Under-Oil Voltage Sensor
High-accuracy voltage sensor for oil-filled medium-voltage equipment
Product Overview
Type UOV sensors are voltage sensors with either 0.5% or 0.3% accuracy for use in medium voltage, oil-filled
electrical equipment including transformers and switchgear. Sensors are required to be immersed in one
of the listed insulaƟng fluids to achieve their electrical raƟngs.
