Undergrounding reduces the risk of faults from severe weather. But it can be challenging to protect underground circuits. The high impact of repeated faults applied by conventional reclosers can damage underground cables, and pad-mounted switchgear primarily distributes power and does not automatically interrupt or isolate faults.
Using low-stress PulseClosing® Technology, S&C’s IntelliRupter® PulseCloser Fault Interrupter gently tests for faults, making it a universal circuit-protection option, even for underground circuits.
