Voltage sensor for gas-insulated switchgear INGEPAC™ SR GR is a voltage sensor based on resistive dividers for gas-insulated switchgear up to 20 kV. It consists of one part designed to be inserted into a type C symmetrical T connector, which contains a high-voltage resistor, and a low-voltage part for connection to the measurement equipment using a BNC connector and grounding. The sensor has a 20000/√3 : 2/√3 transformation ratio and complies with the requirements defined in the IEC 61869-1:2007, IEC 61869-3:2011 e IEC 60044-7:2000 standards. Every unit is individually tested to ensure its accuracy. Voltage metering for gas switchgear Applications ∙ Protection ∙ Medium-voltage line supervision ∙ Metering and power quality High voltage part Cable for sensor’s earth connection Coaxial cable for the sensor’s connection to the measurement equipment High voltage cable Cable for earth connection of the type C connector and the outer mesh of the shielded unipolar high voltage cable
