One of the unwanted effects is the overheating of capacitor banks that are needed to maintain the power factor within the parameters required by the power authority, with a resulting, significant reduction in the average working life. The ideal solution is to insert block reactors in series with capacitor banks.
It is then necessary to verify that the selected capacitors and reactors are suitably sized to limit inrush currents to less than a predefined maximum magnitude, which, for example, is 100 times the rated current, according to IEC 60871-1.
The capacitor has the function of "connecting AC and isolating DC", that is, in the AC circuit, the frequency characteristic of capacitive reactance is used to "connect high-frequency AC and block low-frequency DC". Capacitors are capacitive loads, mainly used to compensate reactive power and store energy.
Explore and interact with GE's High Voltage Capacitors, and learn how these advanced solutions increase capacity, stability and power quality for the grid. A high voltage (HV) capacitor is an electrical device that is used to store high voltage energy in an electrical field.
The common reactors used in the power system areseries reactors and parallel reactors. The series reactor is mainly used to limit the short-circuit current, and it is also used in series or parallel with the capacitor in the filter to limit the higher harmonics in the power grid.
In general, the rated voltage of the partial compensation capacitor is calculated according to the photographic voltage, and the rated voltage of the common compensation capacitor is calculated according to the line voltage. Generally, capacitors are required to be able to withstand at least1.1 times the working voltage.
