TRANSFORMER THEORY:

Transformers are used extensively for AC power transmissions and for several control and indication circuits. As we known of the basic theory of how these elements operate is necessary to know the role transformers play in today's nuclear facilities.

DEFINE the subsequent terms as they pertain to transformers:

a.         Mutual induction

b.         Turns ratio

c.         Impedance ratio

d.         Efficiency

 DESCRIBE the differences among a wye-connected and delta-connected transformer.

  Given the category of connection and turns ratios for the primary and secondary of a transformer and CALCULATE voltage, current, and power for every of the following categories:

a.         ?-?

b.         ?- Y

c.         Y -?

d.         Y - Y
