What is a low voltage power capacitor?
The low voltage power capacitors comply with most national and international standards. Other voltages up to 1,000 V are available on request. Capacitor elements made of metallised polypropylene film are self-healing and dry without impregnation liquid. Each capacitor element is individually protected with patented internal fuse protection.
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.
Are a few low voltage measurements of capacitance compatible?
Only a few low voltage measurements of capacitance are not compatible. Results of the comparison offer the chance to check the calibration and measurement capabilities of the participants in the field of capacitance and dissipation factor measurements, not only for low voltage, but especially for high voltage up to 200 kV.
Do power factor correction capacitors increase harmonic voltage and current?
The application of power factor correction capacitor systems can create unwanted increases in harmonic voltage and current unless the capacitors are properly applied with reactors, in series with the capacitor, to suppress harmful harmonics.
What limiting factors should be considered when switching capacitors?
Two limiting factors must be considered when capacitors are to be switched with a motor as a unit. The first is overvoltage due to self-excitation, and the second is transient torques. Self-excitation voltage: When a motor is disconnected from the line, it will normally rotate for a short time before coming to rest.
