6 FAQs about [Capacitor factory test standards]
Which standard is used to test a power capacitor bank?
ANSI, IEEE, NEMA or IEC standard is used for testing a power capacitor bank.There are three types of test performed on capacitor banks. They are Design Tests or Type Tests. Production Test or Routine Tests. Field Tests or Pre commissioning Tests.
What is a power capacitor design test?
When a new design of power capacitor is launched by a manufacturer, it to be tested whether the new batch of capacitor comply the standard or not. Design tests or type tests are not performed on individual capacitor rather they are performed on some randomly selected capacitors to ensure compliance of the standard.
How difficult is it to calibrate capacitors for use as standards?
Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.
What factors should be considered when evaluating a capacitor protection system?
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.
How to test a capacitor?
Thermal Stability Test. Radio Influence Voltage (RIV) Test. Voltage Decay Test. Short Circuit Discharge Test. This test ensures the withstand capability of insulation used in capacitor unit. Insulation provided on capacitor unit should be capable of withstanding high voltage ensures during transient over voltage condition.
How much voltage should be maintained during a capacitor test?
The voltage once calculated or estimated and applied, it must be maintained with in ± 2 % though out 24 hours of the test period. This test is done at rated frequency and 115 % of rated rms voltage of capacitor. This test is only performed on the unit having more than one bushing.
