Insulation faults in unearthed power supplies can be localised fast and reliably using the portable or permanently installed insulation fault location system EDS. The EDS systemwill pay for itself within a relatively short period by drastically reduced maintenance costs and by avoiding unneccessary costs as a result of operational interruptions.
