Energized Insulator Tester for Distribution up to 35kV

C4032298
ENERGIZED INSULATOR TESTER, THRU 35KV. 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 â„¢ pole with a universal fitting, before each use the tester should be attached to the proper length Hotstick for the system voltage involved. The scale reads up to 11 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 deadend insulators on distribution systems through 35 kV.
Prior to each use, attach to universal fitting on proper length hotstick for the system voltage involved
