ABSTRACT:
The portable live line tool tester of the present invention allows high voltage to be applied to discrete segments of a live-line tool. If the tool has become conductive due to damage or contamination, a leakage meter will detect the flow of current. The tool can then be tested in increments to locate the damaged section. The invention further includes electrical safely interlock circuitry so that the tester is rendered inoperable unless it is correctly rigged and safety shielding is in place. The tester can be folded into an easily portable unit, making it unnecessary to ship tools to a laboratory for testing.
