What is transformer

Transformer means that electrical energy by two or more coils and electrical inductance of a circuit to another circuit via transfers. This means that the current flow in the circuit (the primary) creates magnetic Ykmydan around the first coil, the magnetic field in turn creates a voltage in the secondary circuit is adding a second circuit this voltage can lead to a secondary flow.

Electromagnetic threats

Risks of electromagnetic permanent existence in the space around us, such as natural hazards like lightning and risks such as radar systems, diesel generators, welding machines, wireless or any other radiation, it is increasingly realized the importance of safety, electromagnetic comprehensive.

Autotransformer

Autotransformer (sometimes called "Atvfvrmr" called) so that only one coil is an electrical transformer. Autotransformer coil tap at least three points for the electrical connection that they say. Input voltage and electrical load connected to two taps and a tap at the end of the coil is common. Each pulse may be associated with different voltage sources and load.
