CALIBRATION DEVICE FOR ELECTROSTATIC VOLT- METER

摘要

PURPOSE: A calibration device for an electrostatic volt- meter is provided to reduce a correction error by controlling the angle of electric field generating plate according to the angle of the probe tip of a power outage voltmeter. CONSTITUTION: A base member(110) includes a constant space therein. A field generation board(120) is installed in the base member. The field generation board generates capacitance voltage when receiving a voltage from the outside. A holder(130) is installed in the base member. A capacitance voltage voltmeter(10) is settled in the holder. The capacitance voltage voltmeter measures the capacitance voltage of the field generation board.
