Abstract: The invention relates to a surge arrester comprising two opposing end fittings 3, one or more varistors 5 arranged between the end fittings 3, a winding layer 9 provided at least on the at least one varistor 5, wherein the winding layer 9 is a closed layer 9, and a reinforcement element 7 which extends between the end fittings 3 and keeps the end fittings 3 under tension, wherein the reinforcement element 7 is an open cross winding 13. Moreover, the invention relates to a method for producing this surge arrester.

Abstract: The invention relates to a monitoring device for a surge arrester comprising a means 6 for detecting a total leakage current that is flowing between the surge arrester 3 and earth, a field sensor 9 for detecting an electrical field in the vicinity of the surge arrester 3 and a communication unit 13 for the contact less transmission of data to an external device 2, the communication unit 13 being a near-field communication unit for the contact less exchange of data by means of near-field communication (NFC).
