发明名称 Plug-in electric vehicle charger validation and test device
摘要 A process and apparatus for performing a ground fault test of a device is disclosed. A current level may be selected from a plurality of predetermined current levels. A ground fault current may be generated between a first power line and a ground at the selected current level until a ground fault interrupter within the device trips, or until expiration of an on-time period associated with the selected current level. The ground fault current may then be set to zero for an off-time period associated with the selected current level. The process may be repeated for each of the plurality of current levels. When the ground fault interrupter within the device trips, the current level and a time interval from an onset of the ground fault current at the selected level and a time when the ground fault interrupter tripped may be recorded.

主权项 1. A process for performing a ground fault test of a device that delivers power to a load via one or more power lines, the process comprising: programming a controller to execute, or cause to be executed, the process steps: selecting a current level of a controllable current generator from a plurality of different current levels; generating a ground fault current with the controllable current generator between a first power line of the one or more power lines and ground at the selected current level until a ground fault interrupter within the device trips in response to the ground fault current, or until expiration of an on-time interval associated with the selected current level, whichever occurs first; after generating the ground fault current at the selected current level, setting the ground fault current to zero for an off-time interval associated with the selected current level, and repeating the selecting, generating, and setting for each of the plurality of current levels, wherein: when the ground fault interrupter within the device trips, the process further comprises: reporting the selected current level at which the ground fault interrupter tripped, and a time interval from an onset of the ground fault current at the selected level, and a time when the ground fault interrupter tripped.
