Installation altitude
Up to an installation altitude of 1000 m above sea level, the acceptance need not take the dielectric strength of the
air into account. Above 1000 m, the external insulation measurement of the ISM must be increased by the atmospheric
correction factor Ka according to IEC 62271-1 compared to the insulation measurement at sea level (Figure 59).
Example:
Installation altitude:
2500 m
Operating voltage:
12 kV
Rated power frequency
withstand voltage:
28 kV
Rated impulse withstand voltage 75 kV
Ka factor from diagram
1.2
At sea level the installation must resist the
following test voltage values:
Corrected rated power frequency
withstand voltage: 28 kV x 1.2 = 33.6 kV
Corrected rated impulse
withstand voltage: 75 kV x 1.2 = 90 kV
Please coordinate the necessarily actions
with Tavrida Electric AG.
