6 FAQs about [Norwegian low voltage capacitor recommendation]
Which capacitors should be used in a 400 volt distribution network?
We recommend using capacitors with higher nominal voltage than the nominal voltage of the distribution network. In a 400 V distribution network, we recommend capacitors with a nominal voltage of 440 V and capacitors with a nominal voltage of 480 V for detuned power factor correction with reactors.
What causes a low voltage capacitor?
This effect may be caused by the usage of non-linear devices (generation of higher harmonics), low short-circuit power of voltage sources (voltage fluctuation), etc. We recommend using capacitors with higher nominal voltage than the nominal voltage of the distribution network.
How long does a low voltage capacitor take to de-energize?
Each low voltage capacitor includes discharge resistors to drain residual capacitor voltage to 50 volts or less within one minute of de-energization. The 2400, 4160 and 4800 volt units have discharge resistors that reduce the voltage to 50 volts or less within five minutes.
Are a few low voltage measurements of capacitance compatible?
Only a few low voltage measurements of capacitance are not compatible. Results of the comparison offer the chance to check the calibration and measurement capabilities of the participants in the field of capacitance and dissipation factor measurements, not only for low voltage, but especially for high voltage up to 200 kV.
Do power factor correction capacitors increase harmonic voltage and current?
The application of power factor correction capacitor systems can create unwanted increases in harmonic voltage and current unless the capacitors are properly applied with reactors, in series with the capacitor, to suppress harmful harmonics.
What limiting factors should be considered when switching capacitors?
Two limiting factors must be considered when capacitors are to be switched with a motor as a unit. The first is overvoltage due to self-excitation, and the second is transient torques. Self-excitation voltage: When a motor is disconnected from the line, it will normally rotate for a short time before coming to rest.
