Capacitor Safety Considerations. In this post, I will cover an issue I have recently witnessed regarding the proper specification of capacitors used in safety applications. Specific manufacturer names are not provided as this is unimportant to this conversation. Here is the specification of the capacitor as stated on its datasheet:
These safety recommendations and requi-rements apply to the following power capa-citors and standards. Their purpose is to describe the state of technology which must as a rule be adhered to in all relevant contracts for goods and services. II. General safety rules
The recommendations for the capacitor part are given in IEC 60143-1:2004. Specific information about protective equipment can be found in Clause 3 and 10.6. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision.
describe the state of technology which must as a rule be adhered to in all relevant contracts for goods and services. II. General safety rules Since power capacitors are electrical energy storage devices, they must always be handled with caution.
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.

The rated voltage of a capacitor is limited to 10 000 V. (The operating frequency of the systems in which these capacitors are used is usually up to 15 kHz, while the pulse frequencies may be up to 5 to 10 times the operating frequency.)

voltage vacuum capacitors can generate soft X-rays even during normal operation. Proper containment, fusing, and preventative maintenance can help to minimize these hazards. High voltage capacitors can benefit from a pre-charge to limit in-rush currents at power-up of HVDC circuits. This will extend the life of the component and may
IEC 60143-1:2015 applies both to capacitor units and capacitor banks intended to be used connected in series with an a.c. transmission or distribution line or circuit forming part of an a.c. power system having a frequency of 15 Hz to 60 Hz. The primary focus of this standard is on transmission application. The series capacitor units and banks are usually intended for high …
The new standard currently in force is EN 60252-1: 2011 + A1: 2013; IEC 60252-1 (ed.2); am1. The Amendment A1:2013 introduces the classes S0, S1, S2 and S3 subdividing the previous class P2 into classes S2 (the previous P2) and S3 (new class of security provided only for capacitors with segmented film). For capacitors S3 with segmented film, it ...
As the positioning of this capacitor is also critical, it must meet relevant safety standards and is likewise considered one of the safety capacitors. Depending on requirements, the capacitance value of X capacitors may …
