Abstract - (Show below) - (Hide below)

IEC 60060-1:2010 applies to dielectric tests with alternating voltage; dielectric tests with direct voltage; dielectric tests with impulse voltage and dielectric tests with combinations of the above. This document is applicable to tests on equipment having its highest voltage for equipment Um above 1 kV. The third edition cancels and replaces the second edition, published in 1989, and constitutes a technical revision. The major technical changes with respect to the previous edition are as follows:
- artifical pollution test procedures were removed as they are now described in IEC 60507,
- measurement of impulse current has been transferred to a new standard on current measurement (IEC 62475),
- the atmospheric correction factors are now presented as formulas.
