Answer / iamdon

A power system consists of many circuit elements which can
be approximately modeled as a complicated network(grid) of
Sources, Inductors,capacitors,Resistors etc.The inductor and
capacitor stores energy in their magnetic and electric fields
respectively.

Whenever a power system deviates from its normal operating
condition(due to faualts,perturbations,switching etc)the
redistribution of stored engery takes place.This is because
configuration of circuit changes considerably from pre
perturbation to post perturbation condition.

The redistribution of energy is not an instantaneous
phenomenon.It takes some time(order of micro or milli sec
depending upon the time constants of circuit elements)
to redistribute the stored energy in circuit elements, after
perturbation,which is described by transients in power
system.
