REMARK

1)IEC (International Electrotechnical Commission): An international civilian institute who establishes international standards in area of electric and electronics.

2)Pollution degree: An indicator, which indicates pollution degree, which determine insulation performance of equipment.

*Pollution degree 2 : Normally, only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation shall be expected.
