Overview

The JT-200 Ground Jumper Tester is designed to perform in-service testing of temporary grounding jumper assemblies used on de-energized electric power lines and equipment as specified by ASTM Standard 2249-20E1. The test set is equipped with separate voltage sensing leads to avoid problems related to contact resistance between the test set and jumper under test. The voltage tables have been developed based on values given in ASTM Standard 2249-20E1 and the Terman formula for calculating loop inductance. It is.
