1 Installation category (overvoltage category) describes a number which defines a transient overvoltage condition. It implies the regulation for
impulse withstand voltage. “II” applies to electrical equipment which is supplied from the fixed installation like a distribution board.
2 Applies to measuring circuits connected to low voltage installation, and electrical instruments supplied with power from fixed equipment such
as electric switchboards.
3 “Pollution degree” describes the degree to which a solid, liquid, or gas which deteriorates dielectric strength or surface resistivity is adhering.
“2” applies to normal indoor atmosphere. Normally, only non-conductive pollution occurs.
