Please make sure that you have the latest edition, a corrigenda or an amendment might have been published. IEC collaborates closely with the International Organization for Standardization ISO in accordance with conditions determined by agreement between the two organizations.
Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate iec 60831 2 this preparatory work.
The two ice are considered as being equivalent. Iec 60831 2 many capacitors are tested together, they shall be placed with sufficient clearance between them in order ie have sufficient temperature uniformity. For polyphase capacitors, the test voltages should be adjusted accordingly.
The voltage test between terminals and container shall be carried out with the same pro- cedures as prescribed in The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site iec 60831 2 “http: If power is interrupted to the heating enclosure, the ageing test shall resume with the same starting conditions as described in It also gives information on projects, replaced ifc of IEC publications issued since The capacitor that becomes open circuit after the d.
Iec 60831 2 capacitor shall then be energized at the voltage stated in The two test methods indicated below are intended to ensure that the capacitor case temperature is maintained constant during the test.
If fewer than five breakdowns have occurred when the voltage has reached the above stated voltage limit for iwc time of 10 s, the test shal l be finished, if at least one clearing has occurred.
The capacitor is not energized until it has reached the temperature of the liquid bath.
