Descripción
The dielectric strength of air gaps is affected by air density, humidity and temperature. In order to normalize external insulation strength of power equipment under different conditions, such effects need to be taken into account when external insulation is designed and tested. There are three main applications for atmospheric and altitude corrections: insulation coordination, equipment design and equipment testing. In insulation coordination standards such as in the IEC, the first 1000 m in altitude are included in the recommended voltage levels. In the design of equipment for altitudes higher than 1000 m, atmospheric correction factors exist and must be applied since the conditions at the location of service and in the laboratory where the equipment is tested may be different. This paper presents the continued work of Cigré WG D1.50 and is a continuation of the contributions to the 18th International Symposium on High Voltage Engineering in 2013 in Seoul, South Korea and the 19th International Symposium on High Voltage Engineering in 2015 in Pilsen, Czech Republic. It presents some typical rod-plane short gap test data under DC voltage at different locations with altitudes of up to 1880 m and shows them in relation to the correction curves in IEC 60060-1 (exponent m in relation to factor g). These new test results combined with the results which were the base for the current correction methods could provide the basis for formulating or revising atmospheric and altitude correction methods for short gaps under DC. A possible alternative correction method (by Calva) is also explored in comparison with the IEC method.
