JMTEST.COM • 800.353.3411 68 ELECTRICAL TEST GROUND JUMPER TESTER GROUND JUMPER TESTER NEW PHENIX JT-200 GROUND JUMPER TESTER Portable, Lightweight Simple set-up and operation Ruggedly constructed for years of field and shop use The JT-200 Ground Jumper Tester is designed to perform inservice 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 possible to test more complex jumper assemblies if the voltage drop at 200 A across them is known by adding this number to that obtained from the table. • Main power circuit breaker • On/Off pushbutton switches • Backup circuit breaker for regulator/ transformer protection • Output via interchangeable terminals with voltage sense leads • Zero-start interlock • Operation/maintenance manual Testing Applications Safety and Design Features NEW INPUT 120 VAC, 60 Hz, Single Phase 5 Amps OUTPUT 0-3 VAC, 200 Amps DIGITAL METERING Type / Accuracy 3 ½ digit, 1% of reading ± 5 counts Voltmeter Range 0-3 VAC Currentmeter Range 0-200 AAC DIMENSIONS & WEIGHT Length 20” (508 mm) Width 16” (406 mm) Height 9” (229 mm) Weight 45 lbs.
