This article assesses the technical and economic effectiveness of an intelligent monitoring and high-frequency de-icing system implemented for the Zarafshan-Muruntau 220 kV overhead transmission corridor. The assessment combines operational interruption data, energy not supplied, incident-recovery...

This article evaluates a 3-5 kHz electrothermal method for removing ice from AC-240/39 overhead-line conductors and validates the corresponding transient model against experimental data. The approach applies a frequency- dependent current through a coupling and filtering subsystem so that heat is...
