Abstract

Air gap breakdown voltage is an important basis for the design of air insulation structure, which is related to applied voltage type and voltage waveform. The power frequency AC voltage and DC voltage are collectively called steady-state voltage or continuous voltage. Their change rates are very small, so the discharge development time is negligible compared with the voltage change rate. In this chapter, the air gap breakdown characteristics under steady-state voltage are introduced firstly, and then the air insulation prediction model is used to predict the power frequency breakdown voltages of air gaps with typical and atypical electrodes.
