1 In the U.S., infection with hepatitis C is the most common cause of chronic hepatitis and the most common reason for liver transplantation.
This is a common problem with ABY boxes that do not have isolation. You need an ABY box that has transformer isolation built in like the Radial BigShot ABY, Bones Twin City or Tonebone Switchbone, which is probably the best ABY box ever made.
Medium voltage electronic sectionalizers AutoLink. The ABB AutoLink sectionalizer is an isolating device that automatically isolates the faulted section of the network when a permanent fault occurs. If a temporary fault occurs, the AutoLink allows the upstream recloser or breaker to clear the fault without interrupting the circuit. It is a simple and economic solution for MV overhead lines sectionalizing, towards creating a smart grid and grid optimization.
