The capacitors' life span is calculated by extrapolating the results of an ageing test. The IEC 61049 standard serves as the reference. The following calculation method is used: The ageing test involves submitting the capacitor to a test voltage greater than the rated voltage for a given period of time at the maximum operating temperature.
Power factor correction (PFC) capacitors produce the necessary leading reactive power to compen-sate the lagging reactive power. They should be capable of withstanding high inrush currents caused by switching operations (> 100 x IR).
For commissioning, a current transformer (normally In/5 A) must be installed which matches the total current of the receivers installed. The current transformer's secondary line must have an appropriate cross-section depending on the distance between the transformer and the controller. CORRECT INCORRECT
The IEC 60831 standard stipulates that the capacitors must be capable of operating for 1,500 hours with a voltage 25% higher than the rated voltage, without any short-circuits occurring and with a capacitance loss under 5%. For example, for a 400 V capacitor, the test is carried out with a voltage of 500 V.
As per IEC 60831:2014 capacitors need to be discharged to 75 V within 3 minutes. All capacitors are supplied with a discharge resistor according to the requirements of the standard. Before switching on again, capacitors must be discharged to 10% or less of their nominal voltage. 135,000 hrs. 150,000 hrs. Substantially improved performance (max.
