HV leakage current meter

HV insulated hot line tools online leakage current measurement device

  • The high voltage insulated hot line tools hot stick , ladder & truck boom will be used for hotline maintenance/service of HV line , the leakage current shall be measured before using the hot line tools.
  • The HV insulated hotline tools will be service tested for proof test voltage (leakage current measurement) in 6 months or 1 year time period by Offline method. During Online operations the leakage current may exceed the limit value. Using the leakage current meter, the leakage current in the hotline tools can be measured in the site during hotline maintenance.
  • It is portable & light weight device, can be carried to field/site.
