excellent presentation, I used SMRT simulator using SEL 787 relay.

Very good. Thanks 🙏🙏🙏🙏🙏🙏

Can you please explain why injected currents in 2nd CT is 180° out of phase for Dy1 config?

[@NoHeartAnthony]

he's using a three phase test set, but testing a single phase relay. the current output is a maximum of 30A, but he can get greater than 30A if he also injects using the "second" phase 180degrees out of phase. look at the length of the arrow on the phasor window. the magnitude is from I1 to I2.
