Next, this book discusses special types of transformer connections, such as the zigzag, Scott, and tee connections, as well as the more common wye and delta types. In 3- phase transformer one window contains half of high voltage ( HV) winding and half of low voltage ( LV) winding of two consecutive phase. Electric- Power Networks 10.
Use the load box ( EE 1301) at the output ( balanced resistive load). 4 Losses in core and windings 5 1. 3 Winding Temperature Thermometers. Therefore, if the primary source voltage of a transformer is 7620 volts, the secondary volt- age is 120 volts, and the secondary current, as a result of the load impedance, is 10 amps, then the primary current is 0.
