    • Abstract
  • In view of problem that existing feed state sensor need to be grounded and it is susceptible to interference, a design scheme of mine-used ungrounded feed state sensor was proposed. The sensor wraps signal probes on the load side cable, and uses shield for anti-interference processing of electrode plates, it ensures that the plates and the signal processing circuit use the same reference, and can accurately detect the feed status in the case of ungrounded.
