DERATING FOR ALTITUDE 17 Derating for altitude > 1000 meter over sea level (example) - Installation altitude 2000 m - Working at rated voltage of 7 kv rms - Power frequency 20kV rms - Lighting impulse 50 kvp - Factor Ka = 1.13 (see graph) Those factors can be calculated by the IEC 60071-2 Stds par.4.2.2 with the following equation: Ka = e m (H.1000)/8150 Considering the above parameters, the switchgear must bear (on test at altitude zero i.e. on sea level): -Power frequency: 20 x 1,13 = 22,6 kvrms -Lighting impulse: 50 x 1,13 = 53,5 kvp. From the above it is understood that for installations at altitude of 2000 meters over sea level, with working voltage of 7 kv, it is necessary to foresee a switchgear with rated voltage of 12kV and with insulation lever at power frequency of 28kV rms with 60/75 kvp as lighting impulse voltage.
