“…And these empirical formulas, typical formula as Peek formula, were widely applied. Altitude affect on Conductor corona characteristic was researched, however, test altitudes were not chosen meticulously and systematically, and test data is not abundant [9][10][11][12] . In artificial climate laboratory in UHV AC Test Base of China, six bundle conductors corona onset characteristic was researched systematically in 0m-4000m simulating altitude.…”

Corona cage six bundle conductors corona loss were measured, and corona onset electric field was obtained. The IEC 61284 standard was adopted as altitude correction. And add to this, exponential form and linear form altitude correction formulae were adduced. The results show that, exponential form altitude correction formulae calibration error and dispersion are less, and the adjustment effect is better; for convenient engineering application, linear correction formulae can be adopted; for estimation in the rough, sea level as base, as altitude increases every 1000m, conductor corona onset electric field decreases about 7%.

The corona onset voltage (COV) for bare overhead bundle conductors for transmission lines has been investigated using numerical calculations and the gas discharge theory. First, an accurate numerical method, the charge simulation method, was used to calculate the electric field distribution in the vicinity of bare sub-conductors in bundles. Then the electric field values and a criterion from the gas discharge theory were used to evaluate the onset voltage for negative coronas on the bare sub-conductors. The COVs obtained are in good agreement with literature data for laboratory models and full-scale test lines. Some numerical results for the COV for six-bundle conductors are also discussed.
