How to choose a smoothing capacitor?

The power rating and the capacitance are two important aspects to be considered while selecting the smoothing capacitor. The power rating must be greater than the off load output voltage of the power supply.

What types of capacitors does GE Supply?

GE supplies Low Voltage and Medium Voltage fixed and automatically switched capacitors for power factor correction and harmonic mitigation, in the range of 240V through 13.2kV. GE also supplies active filtering equipment and line/load reactors for specific line and load applications.
