Circuit switchers are a third option utilities can consider for transformer switching and protection. Unlike circuit breakers, circuit switchers are designed and tested specifically for high voltage, ...

Careful selection is vital, with in this case a toroidal mains transformer and good quality capacitors being chosen. The choice between a linear power supply such as this one and a switching ...

In its basic form, the circuit calls for a power supply, a large capacitor, the coil (transformer ... The initial impulse is very powerful—all the energy stored over several microseconds ...

Each transformer must go through rigorous testing before it leaves the plant and makes it to its final destination, wherever that may be. "Our impulse generator, which protects the transformer ...
