Abstract: In a device for automatic testing of power capacitors with high capacitance the tested power capacitor (1) is complemented to the parallel oscillating circuit with the inductor (3) with low losses. The inductor (3) inductance value is selected such that at the testing frequency it has the same reactance as the tested power capacitor (1). To the series combination with the tested power capacitor (1) connected in parallel with the inductor (3) is inserted the first current sensor (2.1) by its input terminals. Its output is connected both to the input of the regulating amplifier (9) and to one input of the phase detector (10). To one of the connections between the parallel oscillating circuit and the output of the power amplifier (6) is connected the second current sensor (4.1) by its input terminals, the output of which is connected to the second input of the phase detector (10). The output of the phase detector (10) is via the integrating amplifier (11) and the voltage-controlled oscillator (8) connected to one input of the adjustable attenuating element (7), while to its second input is connected the output of the regulating amplifier (9). The output of the adjustable attenuating element (7) is connected via the power amplifier (6) to the common connection of the inductor (3) and the first current sensor (2.1) and to the second input of the second current sensor (4.1). For testing of power capacitors with lower capacitance the connection is similar where the tested power capacitor (1) is complemented with the inductor (3) to series oscillating circuit. The inductor (3) is bridged by the first voltage sensor (2.2) connected to the input of the regulating amplifier (9) and to one input of the phase detector (10). In parallel with the series oscillating circuit is connected the second voltage sensor (4.2), the output of which is connected to the second input of the phase detector (10).

Abstract: An apparatus includes a voltage sensor, a current sensor, and a controller. The voltage sensor measures voltage values of alternating current power supplied to a capacitor. The capacitor is electrically coupled to a compressor. The current sensor measures current values of the alternating current power. The controller is configured to receive the voltage values and the current values. The controller is configured to determine a first power factor value based on at least one of the voltage values and at least one of the current values. The controller is configured to selectively detect a first capacitor fault in response to concurrent determination that (i) the first power factor value is less than a first power factor threshold and (ii) a first current value of the current values is greater than a first current threshold. The first capacitor fault indicates that a capacitance of the capacitor has degraded.
