WebHow To Calculate "Turns Per Voltage" and Secondary Current in A Transformer ? Hi Friends, I'm Ramakant and you are watching my YouTube Channel TELE-ELECTRICA... WebTransformer size is determined by the kVA of the load. Load voltage, or secondary voltage, is the voltage needed to operate the load. Line voltage, or primary voltage, is the voltage from the source. Single-Phase has two lines of AC power. Three-Phase has three lines of AC power, with each line 120 degrees out of phase with the other two.
