SYSTEM AND METHOD FOR GROUND FAULT DETECTION AND INTERRUPTION |
摘要 |
<p>A ground fault detector and interrupter for a photovoltaic (PV) energy conversion system, method and apparatus are disclosed. In an exemplary embodiment, the system includes first and second inputs adapted to couple to a first and second rails of a PV array. An inverter is configured to convert DC power generated from the PV array to AC power. A ground fault detector and interrupter, which is coupled to the first and second rails and to the inverter, is configured to detect ground fault conditions in the PV array and to decouple the PV array from the remaining portion of the PV energy conversion system upon such detection. A known signal is coupled to the input of the ground fault detector and interrupter, and then sensed at the output of the ground fault detector and interrupter to determine whether components of the ground fault detector and interrupter are operating properly.</p> |
