Linear loads with low power (such as induction motors) might be adjusted with a passive 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 do opposite acction the distortion and raise the factor. The devices for adjustment of the power factor could be at a central substation, spread out over a dispersion system, or built into power-consuming equipment.
Groups of specially constructed and large, low-inductance are called capacitor banks . Capacitor banks generally are used to accommodate) {$huge pulses of current for many power applications. These contain particle accelerators, pulsed lasers (especially TEA lasers), pulse forming networks, Marx generators, radar, fusion research, and electromagnetic forming.
Mainly, static compensation is not done at line voltage. Transformers bank steps the transmission voltage down to a lower level . This reduces the size and number of components . Although the conductors must be very large to handle the high currents associated with the lower voltage.
Large capacitor banks are used as energy sources for the detonators or specialty weapons or slapper detonators in nuclear bombs. Experimental work is under way using banks of capacitors as power sources for electromagnetic armour and electromagnetic railguns and coilguns.
