The properties of dielectric isolation paper applied in capacitors are studied by using themethod of the time domain dielectric spectroscopy.In conditions of zero field and an appliedfield the complex dielectric constants exhibit obvious differences.There are two values of opencircuit and short circuit for free relaxation time (?)′as well as for random relaxation time (?).Thetwo values of (?)′or (?) may be distinctive as large as six order of magnitude,and they are allvariable if the capacitance of the sample varies,although the sample is made of only the samesort of dielectric material.A reliable method is found out for the measurement of time domaindielectric spectroscopy.
