Shunt compensation:-Shunt reactors with their

compensating effect on the capacitive

generation of the line offers an economical& technically sound means of controllingthe undesirable over voltage.

This topic will focus mainly on the

over voltage under steady state condition& the effect of the shunt reactors on suchover voltage.
