6 FAQs about [Zambia 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.
Can a power capacitor cause resonant circuit?
Systems with higher harmonics content may be sensitive to create resonant circuit between power capacitors and inductance of a transformer and may cause damage of an electrical system. The solution is to use detuned PFC which combines power capacitors with detuning reactors.
How many divisions does ABB Zambia have?
ABB Zambia has five divisions that include power products and systems, discrete automation and motion, low voltage products and process automation. Each division is focused on particular industries and product categories. ABB balances economic, environmental and social objectives and incorporates them into their decisions.
