HV insulated hot line tools  online leakage current indication by detector - Audio & Visual

  • The high voltage insulated hot line tools or hotstick will be used for hotline maintenance/service of HV line , the leakage current exceeding will be detected by the specially designed voltage  detector during the online (live line) operations.
  • The HV  insulated hotline tools  will be service tested  for proof test voltage (leakage current measurement) in 6months or 1 year time period  by Offline method.  During Online operations the leakage current may exceed the limit value. Using the voltage detector shows the leakage current indication when exceeds the set values..
