High-Voltage Capacitance Bridge

QS30b - Shanghai Launch Electric Co., Ltd. (Launch)

QS30b-type high-voltage bridge is newly-designed semi-intelligent high-voltage bridge. It takes use of combined line of current-comparator and Schering bridge. The instrument could measure dielectric loss tgδ and capacitance (C) under AC high voltage for all kinds of insulating oil and insulating materials. It uses straight polarity, testing object insulating to earth.
