High Voltage Capacitors

Increase Capacity, Stability & Power Quality

GE's high voltage capacitors provide simple and reliable reactive power to improve system performance, quality and efficiency. They are designed and manufactured using advanced technology and high-quality materials, and are all-film dielectric units impregnated with biodegradable dielectric liquid.

GE’s high voltage capacitor portfolio includes internally fused, externally fused and fuseless capacitors available in ratings of 25 to 1,100 kVAR for single-phase units, and 300 to 400 kVAR for three-phase units at 2.4 kV to 25 kV. The units can be designed to meet IEC 60871, IEEE 18 and CSA C22.2 standards.

A variety of industries can benefit from using high voltage capacitors for increased capacity, stability and power quality, including applications for power generation, transmission and distribution, as well as power consumers in oil and gas and infrastructure.

High voltage capacitor banks

GE provides solutions for high voltage PFC (Power Factor Control) and filtering. GE’s high voltage capacitor bank equipment is offered in three primary types of fusing schemes: internally fused, externally fused and fuseless. GE can analyze your network thoroughly and help you to choose the design that best fits your specific requirements.

Clearwater

Typical passive solutions

Shunt bank capacitor bank provided optionally with accessories including surge current limiting reactors and switches.

Detuned filter is a power factor solution for networks with harmonics. Series connected capacitor bank and reactor increase the impedance of the circuit at network harmonics reducing capacitor overload.

Tuned harmonic filter provides power factor solutions at fundamental frequency and filters harmonics at a specific frequency. Series connected capacitor bank and reactor create a low impedance path for specific network harmonic(s).

For more information on our shunt bank, detuned filter & tuned harmonic filter solutions, view the brochure and application guide.

Mechanically Switched Capacitor with Damped Network (MSCDN) mitigates undesired network resonances by adding a damping circuit in series with a capacitor bank. For more information view the brochure.

HVDC / FACTS applications

HVDC / FACTS applications

GE’s HV reactive power compensation solutions have extensive experience in FACTS and HVDC, with a large installation base on both. Needs for compensation and filtering equipment in these solutions vary depending on overall design of the equipment, and is typically a combination of different kinds of capacitor banks and filters including:

  • Detuned filter capacitor bank
  • Single, double or triple tuned filter bank
  • High-pass filter
  • C-type filter
  • HV DC capacitor banks

Visit GE’s FACTS and HVDC webpages for more information on these solutions for challenges that the modern power grid faces today.

 

Surge protection capacitors

Surge protection capacitors

GE’s surge capacitors protect the winding insulation of medium voltage rotating machines and transformers exposed to transient overvoltage or surges. GE’s non-PCB power capacitor is an environmentally acceptable product with superior performance and reliability. GE’s protective capacitors contain an all film dielectric system and hermetically sealed bushings, which permits flexible mounting configurations.

Surge protection for:

  • Large motors and generators
