We performed an automatic, demonstration and slightly accelerated measurement of the earth cable insulation resistance with a DC voltage of 2.5kV (i.e. such as should be done in PL) using the new Sonel MIC-2510 meter with the AutoISO-2500 adapter.
Under normal conditions, the measurement should last until the dielectric is fully charged and the resistance value has stabilized (about 60-70 sec for each vein) or according to individual operator / EC requirements (up to several dozen minutes), and the PEN wire should be disconnected from the ground bus in joint and banding. Due to the presentation character of the measurement, this has not been done and therefore, during the last measurement, you can hear the squeaking and information about the activation of the current limiter (LIMIT! = 1mA).
