Abstract

A lightning measuring system (LMS) for measuring lightning current parameters in a down conductor (DC) in a wind turbine is disclosed, said lightning measuring system (LMS) comprising—a sensor arrangement (SEA) being arranged to measure on said down conductor (DC), —a data collection unit (DCU), —a connection arrangement (CA) electrically connecting said sensor arrangement (SEA) with said data collection unit (DCU), and—an insulating arrangement (INS), wherein said sensor arrangement (SEA) and at least a part of said connection arrangement (CA) and/or said down conductor (DC) being enclosed in said insulating arrangement (INS) thereby defining—a minimum insulation distance (MID) between said sensor arrangement (SEA) and said down conductor (DC), and—a minimum surface distance (MSD) between an exposed part of said down conductor (DC) not being enclosed by said insulating arrangement (INS) and an exposed part of said connection arrangement (CA) not being enclosed by said insulating arrangement (INS), for which said insulating arrangement (INS) is effective to prevent insulation breakdown between said down conductor (DC) and said sensor arrangement (SEA) and to prevent surface flashover between said exposed part of said down conductor (DC) and said exposed part of said connection arrangement (CA).
