Capacitor Characteristics – Nominal Capacitance, (C) The nominal value of the Capacitance, C of a capacitor is the most important of all capacitor characteristics. This value measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF) and is marked onto the body of the capacitor as numbers, letters or coloured bands.
The purpose of this specification is to establish minimum requirements for Weld visual inspection for product acceptance of GE Energy Connections (EC) components to detect surface defects on welds, base metal defects caused by weld, or defects in base metal that is repaired by welding.

Capacitor discharge (CD) welding is a form of resistance welding that pulls on energy stored in a large capacitor bank instead of drawing directly from a power distribution network. Because of this ability to rely on stored energy, these projection welding devices have welding times that are short and concentrated, around 12 milliseconds, as ...
