4.5 Other Tests Appendix protection category definition Overvoltage category definition For Australian requirements, in the THDi test, Zref should be added between the inverter and mains. Applies to equipment connected to circuits where measures have been RA, XA for the line conductor Category I taken to reduce transient overvoltages to a low level. - Page 20 Pollution degree definition No pollution or only dry, non-conductive pollution occurs. Pollution Degree I The pollution has no influence. Normally only non-conductive pollution occurs. Occasionally, Pollution Degree II however, temporary conductivity caused by condensation is expected. Conductive pollution occurs, or dry, non-conductive pollution Pollution Degree III occurs, which becomes conductive due to condensation, which is an expected condition.
