rezistans izolasyon: sèvi ak yon Megger nan 500V vòltaj louvri-sikwi li teste rezistans a izolasyon ant chak sikwi a pwen an AC ak pati ekspoze li yo fè, ak ant chak sikwi endepandan, mezire izolasyon rezistans ≥ a 300 mu.

Insulation resistance: use a megger of 500V open-circuit voltage to test the insulation resistance between each circuit of the AC point and its exposed conducting parts, and between each independent circuit, the measured insulation resistance ≥ 300 MÙ.
