Due to their reliability and accuracy, many modern diagnostics based on dielectric voltage response, such as polarization/depolarization current (PDC), voltage decay (VD) and return voltage (RV) measurements, have been used in monitoring ageing processes of metal oxide (MO) varistors. Among these di...
