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.
Capacity [C]: capacitor capacity expressed in μF (microfarad). Nominal voltage of the capacitor [V]: the connection, in series, of capacitor and reactor causes an increase in voltage at the capacitor terminals due to the Ferranti Effect that must be considered in choosing the right component.
Reactor capacity = matching capacitor capacity x reactance rate. For example, if 50kvar capacitor is connected in series with 7% reactor, then reactor capacity = 50kvar x 7% = 3.5kvar. Reactance ratio refers to the ratio of reactance value of series reactor to capacitance reactance value of capacitor bank.
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.
When the reactor is connected in series with the front end of the capacitor, theworking voltage of the capacitor will be increased, and the increase factor = 1 / (1-reactance rate).

Capacitor reveals the state of global fermentation capacity
We see that the most capacity listed on Capacitor is in Europe, with ~21.7 million liters uploaded across 85 facilities. In the Americas ~12.6 million liters of capacity has been uploaded across 75 facilities. Despite having a similar number of facilities, Europe clearly leads the way in terms of capacity scale, managing an additional ~9.1 million liters. In APAC, only ~1.5 million liters has ...

Reactor Sizing for Capacitor Banks
The capacitor should only offset the about 80% of the no-load kVAr of the motor, and not the full-load kVAr. Also, it is dependent on voltage-level, construction-type (open-frame, totally-enclosed, etc). In addition, the capacitor size is inversely proportional to rated-speed!
