power

Linear loads with low power factor (such as induction motors) can be fixed with a inactive network of inductors or capacitors. Non-linear loads distort the current drawn from the system. In such cases, passive or active power factor correction may be used to counteract the distortion and raise the power factor. The tools for correction of the power factor can be at a central substation, spread out over a allocation system, or built into power-consuming equipment.

Groups of large and specially constructed, high-voltage are called capacitor banks or capacitor. Capacitor mostly are used to supply pulses of current for many pulsed power applications. These contain radar, electromagnetic forming, particle accelerators, pulsed lasers (especially TEA lasers), Marx generators, fusion research, and pulse forming networks.

Huge capicitors are used as specialty weapons or energy sources for the detonators or slapper detonators in nuclear bombs. Forward-looking work is under way using capacitor banks as power sources for coilguns and electromagnetic railguns and electromagnetic armour.

This reduces number and the size of components . Regardless of the conductors have to be very huge to manage with the high currents . Mainly, static compensation is not done at line voltage. A bank of transformers steps the transmission voltage (for example, 230 kV) down to a lower level .
