Electrothermal capacitance test capability

Voltage-current method can be used to measure capacity. Equipment: a 5kVA voltage regulator, a voltmeter and an ammeter. The method is to add an appropriate power frequency voltage (about 100V) across the capacitor to be measured, measure the voltage u across the capacitor and the current I flowing through it, and calculate the capacitance (unit μF) according to c = I/(314× u )×100000.
