Transformers Basics, Maintenance and Diagnostics Transformer action depends upon magnetic lines of force (flux). At the instant a transformer primary is energized with AC, a flow of electrons (current) begins. During the instant of switch closing, buildup of current and magnetic field occurs. As current begins the positive portion of the sine wave, lines of magnetic force (flux) develop outward from the coil and continue to expand until the current is at its positive peak. The magnetic field is also at its positive peak. Transformers Basics, Maintenance and Diagnostics

Transformers are devices which use mutual induction to change the voltage and current of an AC circuit. A transformer with primary coil of Np turns and secondary coil of Ns turns will have ratios of voltage and current Vs Ns Ip ---- = ---- = ---- Vp Np Is Jargon: Ns > Np step-up transformer Ns < Np step-down transformer Viewgraph 1 Transformers and Long-Distance Power Transmission
