How Capacitors Work
A capacitor''s storage potential, or capacitance, is measured in units called farads. A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons.
Capacitor Voltage Transformer (CVT Or CCVT)
The main applications of CVT in High Voltage Networks ( above 36 kV ) are given below.Tap voltage (approximately 5-12 kV depending on the type) is taken from the lowest capacitor section and fed to an electromagnetic circuit in the cast aluminum base box.
