A transformer transfers electrical energy from one system to another by induction. Except for grounding and bonding connections, there’s no physical connection between the two systems. For this reason ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

There are a number of potential solutions to the classic EMC problem of providing immunity from mains borne interference, especially in the form of surges, sags, brownouts, lightning strikes and noise ...
