Applies to the construction and use of sphere-gaps for measuring the peak value of alternating, direct and both full standard and longer tail impulse voltages. Peak values of the disruptive voltages in air are given in tabular form. Note: - For high-voltage test techniques, see IEC 60.

Describes a continuous test at a steady temperature of 40°C and a relative humidity of 90-95%. The standard test duration is 4 to 56 days.

Applies to three-phase turbine-type machines, with rated outputs of 10 MVA and above, used as generators.
