It is the angular setting provided between the reference voltage and operating current beyond which the relay will operate. During the normal operating conditions, the MTA should be adjusted to cos theta= 0. so the angle should be 90 degrees. But once any forward side fault occurs in the system, the angular difference will be less than zero so the operating quantity will be more than restaining quantity.

What are the difference between normal application Transformer and Solar application Transformer?
if there are six generators (3 gas CATT, one Jenbacher o1 MW each, and two nos Diesel 01 no 01 mw other 0.65mw EDGs ( say), 3 CAtt gas set have identical pole pitch,01mw EDG and Jenbacher gas Set have different pole pitch, how their power connection can be done to connect a common bus bar during installation. in short, how different pole pitched generators power connection can be done to connect a common busbar system through generators incomer ACBs.
