Abstract
A method of controlling a static VAR compensator includes providing a static VAR compensator having a capacitive component and a thyristor for switching the capacitive component into and out of a power distribution network; monitoring an electrical characteristic associated with the capacitive component; and controlling operation of the thyristor at least in part on the basis of the electrical characteristic associated with the capacitive component.
