Summary:
The TL (transmission lines) and the GW (ground wires) ice covering represents a danger to the power systems operation. When the ice-melting procedure using a rectifiers is conducted, an accidents due to the induced EMF in the GW from the TL currents are possible. In this paper the induced EMF values are calculated for different TL operation modes, different positional TL relationship and different ice-melting diagrams. In addition, a methodology of the induced EMF value calculation in the GW is described, a comparison of the EMF values for different TL operation modes and different ice-melting diagrams is made, and possible dangers during the ice-melting procedures are noted. A ways to improve the calculation methodology are listed.
