A two‐stage approach to shunt capacitor‐based
To sustain healthy systems when shunt capacitors are placed, the optimal site(s) and size(s) has to be determined; else improper siting and sizing do not only diminish the anticipated benefits, but also endanger the control mechanism of

Power factor correction
Correction capacitors provide needed reactive power (kVAr) to the load. If some thing happened by an Inadvertent mistake, and the compensated reactive (capacitive) power is more than the inductive power, then the load is going to be capacitive, so what are the effects of this (capacitive) load on the MV and LV distribution network?
Overcompensation of series capacitors
Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In other words, in series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system.

When reactive power devices, whether capacitive or inductive, are purposefully added to a power network in order to produce a specific outcome, this is referred to as compensation.

Compensation for power factor means adding some capacitive reactance to compensate for the usual inductive reactance. Fixed capacitors

- Inflexible adjustment: Passive compensation devices provide fixed compensation, which does not adjust automatically in response to changing loads. - Risk of overcompensation: When the load changes, capacitor banks may overcompensate, leading to
Overcompensation of reactive power for induction motors
The recommended practice is to size the capacitor to around 80% of the reactive power demand at no load condition. Overcompensation of motors is often is not intentional and usually happens when motors are relocated to a new starter location or when swapping motors with different magnetizing characteristics.

Treating a speaker as a resistor, a capacitor, or an inductor
The problem is the 1.5" mid cannot reproduce any lower frequency. So the dual 10" woofers have to be crossed over at higher point, approx. 800Hz. And I found that in order to boost bass, reducing mid and high outputs, the dual 10" were lifted all their operating range, not only bass region but mid-bass region.
Understanding probe compensation
In the case of either over- or under-compensated probes, the compensation capacitor is adjusted until the waveform has nice, square edges. This usually takes only a very small fraction of

Series Compensated Line Protection
Series capacitor banks are made up of series and parallel combinations of capacitor elements as required in order to achieve the desired bank rating. This chapter shows that the relay protecting a series compensated transmission line is presented with changing information following the incidence of a fault.
How does over compensation affect the bill?

Compensation capacitors are used to counteract reactive current (increased power factor) and are basically either connected in parallel or in series. Compensation capa-citors are not required when using electronic ballasts, whose power factor is generally in the region of 0.95.
How does over compensation affect the bill?
The utility usually doesn''t care if the system is slightly capacitive, but consistent excessive leading PF may cause them to notice. As far as the overcompensation, if it is a fixed bank, that is, it doesn''t have steps that close in and out as the reactive load changes, the capacitor bank may be too large for the application.

capacitor
Compensation for power factor means adding some capacitive reactance to compensate for the usual inductive reactance. Fixed capacitors means that you may have to pick certain discrete values so you can decide to leave the load as somewhat inductive (undercompensated) or capacitive (overcompensated).

6 FAQs about [Whether the capacitor is over-compensated or not]
When should a capacitor be sized to overcompensate a motor?
The recommended practice is to size the capacitor to around 80% of the reactive power demand at no load condition. Overcompensation of motors is often is not intentional and usually happens when motors are relocated to a new starter location or when swapping motors with different magnetizing characteristics.
What happens if a power factor correction capacitor is too high?
If the power factor correction capacitor is sized higher than the recommended value, then there a possibility that the motor magnetizing inductance and the power factor capacitors form a resonant circuit as the motor is switched off and is slowing down.
What is the difference between capacitor-a and capacitor-B?
Referring to the graph below, Capacitor-A is sized to less than 80% of the reactive power demand of the motor. The capacitor-A graph will never intersect the motor magnetizing curve and there will not be any adverse effects. On the other hand, Capacitor-B is sized higher than the reactive power demand of the motor.
What is a fixed capacitor?
Fixed capacitors means that you may have to pick certain discrete values so you can decide to leave the load as somewhat inductive (undercompensated) or capacitive (overcompensated). If the load inductance varies during operation then again you may have to pick some intermediate value and the cancellation may be fairly imperfect.
What happens if a capacitor bank size is higher than a motor?
The capacitor-B current is greater than the motor magnetizing current. It can also be observed that a stable operating point (at 130% voltage in this example) is possible with the higher capacitor bank size. This operating point can occur when the motor is switched off and the motor speed is slowing down.
When are series capacitors effective?
Series capacitors are very effective when the total line reactance is high. Series capacitors are effective to compensate for voltage drop and voltage fluctuations. Series capacitors are of little value when the reactive power requirements of the load are small.
