IntelliRupter^® PulseCloser vs. Recloser Demonstration

The videos below capture a laboratory demonstration of the IntelliRupter PulseCloser responding to a permanent phase-to-phase fault. IntelliRupter is configured in two different ways. First, the IntelliRupter is configured to behave similar to a conventional recloser, and can be viewed in both regular speed and slow motion. Then, regular speed and slow motion videos show how IntelliRupter responds to the identical fault event when it is configured to test the line for faults using pulseclosing. Note the dramatic reduction in arcing produced by using pulseclosing instead of simply closing into the fault. Each delayed recloser operation results in 10 cycles of fault current, while each pulse results in only 5 ms of reduced magnitude fault current. Since the fault is permanent, the end state is lockout for both configurations.
