Power (watts) = Current (amps) X Voltage (volts) P=IE
Section 4.2 – Transformer and Transformer Protection Overview Power (watts) = Current (amps) X Voltage (volts) P=IE Transformers change voltage to usable values Dry and wet types – cooling mechanism Dry – Smaller, Wet – Larger EFI – Electrical Field Interference – Monitors, TVs Rating basis on K Factor – volt-amps K Factor identifies load capacity
