power

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

This reduces the size and number of components . In spite of the conductors must be very large to handle the high currents associated with the lower voltage. In most cases, static compensation is not done at line voltage. Transformers bank steps the transmission voltage (for example, 230 kV) down to a lower level (for example, 9.5 kV).

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

Large reservoirs are used as slapper detonators in nuclear weapons or energy sources for the detonators or specialty weapons. Forward-looking work is started using capacitor banks as power sources for coilguns and electromagnetic railguns and electromagnetic armour.
