<p>PROBLEM TO BE SOLVED: To provide a capacitor-current measuring apparatus, which suppresses the inductance of a parallel conductor to be low and which measures a current primarily without the need for labor. SOLUTION: The capacitor-current measuring apparatus measures the current of a capacitor, which is connected to a large-voltage and large-current circuit and one end of which is grounded. The measuring apparatus is provided with a voltage divider (4a), which divides the voltage across a grounding point and the other end of the capacitor and a computing means (20), where the voltage, with reference to the grounding point, divided by the voltage divider, is differentiated, an the obtained differential value is multiplied by a factor which takes into account the voltage-dividing ratio of the voltage divider and the capacitance of the capacitor, and the current of the capacitor is computed.</p> |
