Since the absence of particular standard

the design and testing procedure of voltage protection capacitors

which is used to suppress the impulse overvoltage in power system

has to refer to the standard of shunt capacitors in a long term.In this paper

the comparative analysis of these two kinds of capacitors is made at the aspects of installation location conditions

protection measures and operation characteristics.It is shown that the standard of shunt capacitor standard is not applicable to the voltage protection capacitor

whilet the standard of coupling capacitor can be adopted.Moreover

two issues to be paid attention are proposed

which is helpful in safe operation of voltage protection capacitor.
