Attention should be paid to the following aspects in the installation of low-voltage compensation power capacitors to avoid damage during installation and early damage of capacitors.

1. When installing the low-voltage compensation power capacitor, an independent soft copper wire should be used to connect with the bus duct at the connection point of each capacitor to avoid the capacitor from being damaged due to excessive copper wire.

2. When installing, be sure to maintain good contact between the circuit of electrical equipment and the grounding protection device, so as to avoid early damage of the capacitor caused by high-frequency oscillation arc of the capacitor.

3. When the low-voltage compensation power capacitor with lower voltage level is connected in series and operated in the Internet with higher voltage level, the insulation layer should be reliable according to measures such as refitting insulators equal to the operating voltage level in the middle of the casing of each unit.

4. After the low-voltage compensation power capacitor is connected in a star shape, the casing of the low-voltage compensation power capacitor will solve the ground insulation layer when the rated current is higher and the neutral point is ungrounded.

5. Before installing the low-voltage compensation power capacitor, the capacity should be tested to make it phase-balanced, and the error should not exceed 3% of the total capacity. When equipped with a relay protection device, it should also be considered that the deviation of the balance current during operation does not exceed the provisions of the posture current of the relay protection device.

6. The wiring of some low-voltage compensation power capacitors shall ensure that: for the magnetic induction motors that are started immediately or started by electromagnetic relays, the power capacitors that improve the power factor can be immediately connected with the small-group outlet terminals of the motors, and there is no need to place switching devices or fuses between them.
