Research on Control Measures for Steady-State Power Frequency Overvoltage of Half-Wavelength Transmission Lines

2019 4th IEEE Workshop on the Electronic Grid (eGRID), 2019
The half-wavelength transmission line (HWTL) is a forward-looking and competitive solution for transcontinental and transnational power transmission. The problem of steady-state power frequency overvoltage of HWTL is serious. It is a matter of great concern in the safety and stability analysis of the power system connected with the HWTL. In this paper,

Frequency of flashovers of clearances in low‐voltage ac power circuits due to overvoltage waves

European Transactions on Electrical Power, 1995
AbstractThe frequency distribution of the crest values of overvoltage waves in low voltage AC power circuits can be approximated by an exponential function. The flashover probability P of a clearance with an impulse withstand voltage Ǔst in an electrical equipment is given by P= exp (‐ α Ǔst). The annual number of flashovers of a single clearance in an
