WebThe reason why you would do a megger test (which tests insulation quality of the wires) is lightning is extremely powerful, enough to actually damage the insulation from heat generated. If that insulation is damaged, there can be cracks where there could be parallel arcing (arcing between the hot and neutral). Web18 aug. 2024 · Step 5: Then connect the L terminals of the megger to the line of the conductor itself while the E terminal to the Earth terminal of the conductor. And G terminal to the ground.. Step 6: Then used the handle of the megger to generate emf to the line, by turning the handle at a speed greater than 120 r.p.m. and watch the pointer as it reads …
