The capacitor shall also withstand a 1 minute power frequency withstand test of a test voltage applied between the capacitor terminals and earth. For 12 kV rated capacitors, the test voltage is 75% of 28 kV. Refer to IEC 60871 or AS 2897 for other ratings. The requirements of the test are satisfied if no disruptive discharge occurs.
In making this evaluation, consideration must be given to the sensitivity of capacitor bank protection (such as unbalance protection) and the potential for a capacitor under test to inadvertently discharge stored energy into a protection system. In most cases secondary isolation of the protection system will be required.
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.
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.)
Inspect the external surfaces and ensure the capacitor units and reactors are clean and dry. Check that primary connections are correct. Check earthing to capacitor bank mounting frames and enclosure. 5.6. Measure Insulation Resistance Insulation resistance tests as listed below are to be applied for one-minute duration each.
Welcome to the Capacitor Fundamentals Series, where we teach you about the ins and outs of chips capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about the right capacitors for your specific applications.
