Energized Transmission Tester

Item Number: C403-2299 Category Search Terms , , , Brand:

(44kV – 500kV). A sensitive voltmeter, the tester measures the difference in potential across each insulator in a suspect string. Comparative readings from satisfactory strings in the same operating situation quickly indicate the state of every insulator in the string being tested. The meter places only a minimal load on the phase as it requires only a small leakage current to make a reading. Two straight steel probes threaded into the tester forks simply contact the metal fittings on both ends of each insulator at the same time. Mounted on a 1.25″-diameter Epoxiglas® pole with a universal fitting, before each use the tester should be attached to the proper length hot stick for the system voltage involved. The scale reads up to 16 kV.

  • Applications Without interrupting service, one of these testers quickly can check the condition of each insulator in a string.
  • This greatly reduces maintenance costs.
  • Rather than changing out entire strings, only the insulators identified as damaged require replacements.
  • The testers serve specific applications for suspension insulators on 44 kV through 500 kV transmission systems.
