The A-ISOMETER® iso-F1 monitors the insulation resistance between the active conductors of an electrical drive system (Un = DC 0…800 V) and the reference earth (vehicle mass). The patented measurement method is used to monitor the condition of the insulation on the DC side as well as on the AC side of an electric vehicle with drive system and to signal insulation faults reliably even under high system interferences which can be caused by motor control processes.
