Damage Types and Rules of Capacitors

There are many types of capacitor damage, which can generally be summarized as follows:

1. Initial failure. This means that a failure occurred shortly after power transmission or power transmission, which is mostly caused by poor manufacturing processes or serious defects.

2. Occasional malfunction. This refers to damage caused by poor ventilation and overheating, external force destruction, operation overvoltage or lightning.

3. Abrasion failure. This is the cause of the damage caused by the decrease in the strength of the insulation due to aging of the insulation and the internal release of the capacitor after many years of operation.

The general rule of capacitor damage is:

1. There are more high voltage capacitors than low voltage capacitors.

2. Summer is more than other seasons.

3. Installed outdoors more than indoors.

4. In the frequent over-voltage and overload conditions, the operation is more damaged.

5. Frequent damage to the switch operation is more.

6. Poor management and maintenance, poor ventilation, and more damage.
