This reduces number and the size of components . In spite of the conductors have to be very large 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 (for example, 9.5 kV).
Groups of specially constructed and large, high-voltage are called capacitor banks . They generally are used to supply vast pulses of current for many pulsed power applications. These include electromagnetic forming, radar, fusion research, particle accelerators, Marx generators, pulsed lasers (especially TEA lasers), and pulse forming networks.
Non-linear loads distort the current drawn from the system.Linear loads with low power could be fixed with a inactive network of inductors or capacitors. In such cases, active or passive factor correction might be used to counteract the deformity and raise the power factor. The tools for correction of the power factor may be at a central substation, spread out over a dispersion system, or built into power-consuming equipment.
Large capacitor banks are used as energy sources for the exploding-bridgewire detonators or specialty weapons or slapper detonators in nuclear bombs. Unconventional work is under way using banks of capacitors as power sources for electromagnetic railguns and electromagnetic armour and coilguns.
