The dielectric response analysis method is based
on broad range measurements in time and
frequency domain. The used methods in time
domain are polarization/depolarization current
(PDC) and recovery voltage (RV) measurements
and in frequency domain the dissipation factor
tan() and the complex capacitance C()
measurements. All of the dielectric spectroscopy
methods are based on measuring the conduction
and dielectric polarization response in time and
frequency domain and they should provide
equivalent results in theory if the dielectric
material can be described as a linear system. In
this case the measured data can be transferred
from one domain to another. This is important
for high voltage insulating materials because it is
in many cases easier and more accepted to
interpret data in frequency domain than in time
domain [6]
