Huge reservoirs are used as energy sources for the detonators or slapper detonators in nuclear weapons or specialty weapons. Experimental work is under way using capacitor banks as power sources for electromagnetic railguns and coilguns and electromagnetic armour.
Groups of large and specially constructed, low-inductance are called capacitor banks or capacitor. They generally are used to accommodate) {$huge pulses of current for many power applications. These contain particle accelerators, electromagnetic forming, Marx generators, pulse forming networks, fusion research, radar, and pulsed lasers (especially TEA lasers).
Linear loads with low power factor (such as induction motors) may be fixed with a passive network of inductors or capacitors. Non-linear loads (such as rectifiers) distort the current drawn from the system. In such cases, active or passive power factor correction might be used to counteract the distortion and raise the power factor. The devices for adjustment of the power factor can be at a central substation, spread out over a allocation system, or built into power-consuming equipment.
In most cases, 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). This reduces the size and number of components . In spite of the conductors have to be very large to handle the high currents associated with the lower voltage.
