UNIT 1 OVER VOLTAGE IN ELECTRICAL POWER SYSTEM …
www.bharathuniv.ac.in2. Indirect lightning strokeS LIGHTNING ,SWITCHING AND TEMPORARY OVER VOLTAGE over-voltage-spike Over voltages are caused on power systems due to external and internal influencing factors. The voltage stress caused by over voltage can damage the lines and equipment’s connected to the system.

www.bharathuniv.ac.inθ 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:
