Insulation diagnosis is important to High Voltage Equipment
such as transformer, power cable and rotating machine.
Conventional methods such as Insulation Resistance (IR) and
Dielectric Dissipation Factor (DDF) have been part of the
diagnostic testing for the last decade. Although these methods
are useful in determining the general condition of the
insulation, nevertheless isolating the causes of the
deterioration of insulation require more detail analysis. The
analysis includes the behavior or responses of the insulation
under static or varying electric field. In this paper, the author
will review one of the technique called polarization
depolarization current (PDC) that will look into the dielectric
responses under static electric field (DC) in order to diagnose
the condition of various high voltage equipment such as power
cable, transformer and rotating machine. Theory on the
technique will be explained in the beginning, followed by
parameters used by other authors in evaluating the condition
of insulator. Finally, the author will share three case studies
that based on field experience in determining the condition of
insulation for rotating machine, transformer and power cable
using PDC technique. |
