Electric Vehicle Ground Fault Detection. If measured insulation resistance declines below a set value, an alarm is issued. The electric systems in electric vehicles are ungrounding, so the first ground fault is not dangerous.
This paper discusses a method for detection and localisation of the insulation faults in electrical equipment distributed along the body of electric and hybrid electric vehicles. To avoid false alarms due to ground fault detection when using this method, fault counting is necessary over a period of time.
