Consider a 15/5 A CT with primary winding number of
turns of 37 and secondary winding number of turns of 119 . The
secondary winding resistance is given as 0.154 ohms and the
secondary winding reactance is known as 0.201 ohms. CT- Relay
connecting lead resistance is 0.17 ohm. The magnitizing AT is 13.8
and the loss AT is 10.2 . The Burden is defined as 15 VA at 5A with
pf of 0.6 lag.
a) Find the ratio error
b) Find the phase angle error.
