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 high-voltage capacitor is a capacitor with a withstand voltage greater than twice the actual working voltage. In the oscillating circuit, oscillating components, phase shifting network components, filters, and the like should be connected with a high-voltage capacitor of a small temperature coefficient to ensure good performance.
Performance specifications for high voltage capacitors include capacitance range and capacitance tolerance, a percentage of total capacitance. Working DC voltage, insulation resistance, dissipation factor, and temperature coefficient are additional considerations.
High voltage capacitors are packaged in tape reels, trays or rails, shipping tubes or stick magazines, and in bulk packs. Tape reel assemblies include a carrier tape with embossed cavities for storing individual components.
A high quality capacitor (high Q-factor) will thus have low values of dissipation factor (DF) and loss tangent (tan δ), i. e. less losses. The most commonly used bridges for capacitance measurement are De Sauty’s bridge and Schering Bridge. 6. 5. 1 De Sauty’s Bridge.
Commercial-off-the-shelf (COTS) grade capacitors are cost effective and readily available options. They are widely used in various industries, including aerospace and military applications, due to their high reliability. Using COTS capacitors helps electronic systems designers create small and light-weight electronic assemblies.
