What should a capacitor bank have?

The capacitor bank should has two technical drawings, namely, main circuit diagram and control circuit diagram. The main circuit diagram should provide information how to connect the capacitor bank to the supplying switchgear: There is three phase network incoming to supply the capacitor bank (Low Voltage switchgear).

How to protect a capacitor from a short circuit?

The short circuit protection of the capacitors is provided by the switch disconnectors. For the capacitors the fuse link rated current should be 1.6 time of the rated reactive current of the capacitor. In=Q / (Un×√3) where: Q – rated power of the capacitor at rated mains voltage.

Why are capacitor banks installed?

Capacitor banks are mainly installed to provide capacitive reactive compensation/ power factor correction. Normally in factories or other high power consuming places, most probably there will be a consumption of the inductive load. Inductive voltage means that there must be a lagging power factor.

How to select a contactor for a capacitor?

In order to select proper contactor for each capacitor, one needs to pay attention for the rated power that can be handled by the device at given rated voltage. Therefore, for the project, where there are capacitors of rated power of 20kvar and 40kvar, following contactors were selected: MC – 32 and MC – 50.

Where should a capacitor bank be placed?

If the capacitor bank is to be placed in the same place as the main switchgear or utility room next to it, IP 20 is enough. Section construction – in a device for reactive power compensation particular sections can be determined, placing them in separate partitions or within the same cubicle. 1. Enclosure

How to choose series of capacitors for PF correction?

Considering power capacitor with rated power of 20 kvar and rated voltage of 440V supplied by mains at Un=400V. This type of calculation is true, if there is no reactor connected in series with capacitor. Once we know the total reactive power of the capacitors, we can choose series of capacitors for PF correction.
