Detection of Failures in Metal Oxide Surge Arresters Using Frequency Response Analysis [PDF]
This work presents an innovative application of Frequency Response Analysis (FRA) in order to detect early degradation of Metal Oxide Surge Arresters (MOSAs). This technique has been widely used in power transformers, but has never been applied to MOSAs.

Quality Assessment of Low Voltage Surge Arresters
Users expect reliable operation of the surge arrester during overvoltages, which may originate from a switching process or a lightning discharge. The necessary conditions to guarantee these expectations are: appropriate construction of the surge arrester,

Efficient replacement of the radioactive sources in the gas-filled surge arresters construction for the insulation co-ordination at the low voltage level [PDF]
The possibility of the classical response rate engineering and the long-term deconditioning of the gas-filled surge arresters is considered in this paper. The obtained results are compared with the same results obtained with the gas-filled surge
