Why does the transformer stop and switch the neutral point grounding knife on each side?
The transformer is composed of an iron core (or magnetic core) and a coil, and the coil has two or more windings, wherein the winding of the power supply is called a primary coil, and the rest of the winding is called a secondary coil (two or more). In a generator, whether coil movement through the moving magnetic field or magnetic field through the fixed coil, can induction voltage in the coil, the two kinds of circumstances, the magnetic flux values are unchanged, but with the coil intersection chain flux quantity is changed, this is the principle of mutual inductance should. A transformer is a device that uses electromagnetic mutual inductance to change voltage, current, and impedance.
The transformer is the device transform AC voltage, current and impedance, when there is communication through the primary coil current, the core (or core) will be generated in the exchange flux, the secondary coil induces a voltage (or current).
Requirements are the prevention circuit, residual charge, wounding, anti - delivery fault, wounding, second power misoperation, live wounding, these circumstances. Its grounding side is the primary access cable of the transformer, and switching operation between the switching equipment is not neutral.
