How to operate the reactive capacitor module
Having above information, it is possible to find fitting cubicle for the elements of the capacitor bank. Because the device is going to operate at the mains, where higher order harmonics are present, power capacitors must be protected by reactors. Each capacitor emits additional amount of heat as well as a reactor. The. The arrangement of the elements inside the enclosure should be easily available for maintenance and replacement, and each element should be clearly marked according to the technical documentation. In the project, in terms of. The next step is to chose appropriate power capacitors. It means, that one needs to pay attention to its rated voltage and power. Since the capacitors will be working in series with reactors, what will cause the voltage at the. The last step is to select the protection of the capacitors as well as the contactors. In order to do so, one has to skim the catalogue cards of the. 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. -
