2. BATAS – BATAS DARI TAHANAN ISOLASI KUMPARAN TRAFO

Menurut standard VDE (catalouge 228/4) minimum besarnya tahanan isolasi

kumparan trafo, pada suhu operasi dapat dihitung sebagai berikut :

1 kV = 1 MΩ

Catatan : 1 kV = besarnya tegangan phase terhadap tanah.

Kebocoran arus yang diijinkan setiap kV = 1 mA.
