Backfeed Test Of Vertical Fuse Disconnector

Therefore, a reverse current test was conducted on one of the strings in vertical fuse switch disconnector. A voltage differential was maintained between one of the strings in nhrt40 vertical fuse switch disconnector and the other four strings in the same MPPT path. This voltage differential caused current to flow back into the faulty string from the remaining four strings, reaching 30A. Three rounds of testing were conducted under these conditions.
