ang megger po ay ginagamit para masiguro na walang short circuit ang dalawang wire or mababa ang resistance between them. minsan kasi kahit gamitan mo sya ng simpleng ohm meter to verify if shorted nga sila hindi mo makukuha o masusukat mo lang sya as open or not shorted. gaya ng naranasan namin noon laging bumibigay ang ckt breaker pero ng sukatin namin ng simpleng tester to check if theres a short wala naman syang mabasa or open. but when we try to check it in megger bagsak sya sa reading. i cant remember kung ano yung reading nya pero dito sa amin ang acceptance reading nya is 15M ohms up.. babad kasi sa tubig ung wire na papuntang ckt breaker anyway open all the source before you test the wires. anyway try to search here in the forum what is the difference between megger and hi-pot..

megger (megaohm meter) = insulation tester.

ginagamit sa mga high resistance measurements. connected line-to-ground (for motors), line-to-line and line-to-ground (for electrical wiring installation).

Plus 1. If ang operating voltage eh 440vac. ang minimum insulation eh 1.44megaohms. Pero kanya kanya ng standard yan. Wink

gumagamit sya ng highvoltage para masukat ang resistance, ingat baka madale Grin at maibasibas mo ang megohm meter mo Grin Grin Grin
