safety and quality should be the top priori-ties when a capacitor is selected. This is why we urgently recommend the use of capacitors with appropriate internal pro-tective devices. 2. Before designing the application, capaci-
Visually inspect the capacitors. Check the protection fuse. Control the ambient temperature (average of 35 °C. In accordance with IEC 60831). Keep the capacitor terminals clean. Verify the state of the contacts of operating elements.
If the capacitor bank has an autotransformer, check that it is in good condition and shows no signs of deterioration. Force the connection and disconnection of the capacitors in manual mode. (refer to the regulator’s manual before carrying out these actions) and perform the following checks.
There is no estimated time frame for cleaning, it depends on the amount of dirt that is inside the capacitor bank. Inspect the cables and terminals. They should not be overheated or blackened. The terminals must be clean. The slow discharge resistors must be in good condition. They must not be open or show signs of burning.
Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance. or their behavior in the event of a fault. perature) should be monitored within the application. 8.
Even if the test based on the capacitor standard is passed, this does not ensure comprehensive protection against all pos-sible overloading. Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance.

Safety Recommendations
• When power capacitors are used, suitable measures must always be taken to eliminate possible danger to humans, animals and property both during operation and when a failure occurs. This applies to capacitors both with and without protective devices. Regular inspection and maintenance by a competent person is therefore essential.
