The process of insulation coordination of power systems is conditioned by a number of factors, among which the improvement of methods of surge analyses occupy a special position. The use of statistical procedures in coordination of insulation of overhead power lines requires knowing statistical distributions of surges and reliability of their parameters. Establishing the type of distribution and the...
This paper presents an iterative calculation method which enables the dimensioning of indoor air clearances for High Voltage Direct Current (HVDC) converter stations for the purpose of insulation co-ordination based on simulated or calculated impulse (withstand) voltages. For this aim mainly normative procedures mentioned within several AC or test standards are used and combined to promote method...
