UNIT I - INTRODUCTION OF RELAYS

θ is the angle by which S 2 lands S 1.If β 1 = β 2 =90 o, the comparator is called cosine comparator and if β 1 =0 and β 2 =180 o, it is a sine comparator. In short, a phase comparator compares two input quantities in phase angle (vertically) irrespective of the magnitude and operates if the phase angle between them is < 90o. There are two types of phase comparators:
