is connected to earth). The insulation resistance has to be at minimum 1 MΩ according to the IEC 60364-6 and IEC 61.3.3 standards. NOTE: Use a megger rated at 500 Vdc if Ue ≤ 500 Vdc or 1000 Vdc if Ue > 1000 V (DC to avoid capacitive currents). Carry out a general visual inspection of the earth network. In particular check: that the galvanized steel casing sides are earthed. This depends on the earthingsystem. the connection quality.  the cable cross-section.  there are no loose metal parts (washers, screws) in the tap-off units.(1) No neutral insulation check is required if the earthing system is such that the neutral is connected to or used as the earth.68QGH3492101-01 11/2018Commissioning and MaintenanceStepTestDescription5Transformer and switchboard connections check Reconnect each link to the upstream transformer.
