Abstract

In the past, conventional methods for condition monitoring (discussed in the previous chapter) have enabled power utilities to anticipate developing problems and plan maintenance activities accordingly. In recent past, new non-invasive diagnostic methods have been proposed which are complimentary to classical electrical measurements. These methods are based on measurement of dielectric response of transformer insulation in time domain, viz. measurement of polarization and depolarization currents (PDC) and recovery voltage measurement (RVM), or in frequency domain, i.e., frequency domain spectroscopy. This chapter elaborates the two methods of time domain dielectric response measurement—namely PDC and RVM.
