Modeling metal oxide surge arrester for the modern polarization based diagnostics [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2005 Recently a number of new non-destructive diagnostic techniques have been investigated for the reliable condition assessment of the ageing of metal oxide surge arrester (MOSA). Among them polarizationrdepolarization current and return voltage measurement techniques showed very promising results.
