Distance protection and automatic reclosing on 400 kV transmission line with classic and compact towers

The paper presents an example of modeling high-voltage line with classical columns and pillars compacted with the same lines and testing out the model in the programming tool DIgSILENT with actual measured data for Single Line to Ground Fault with the use of ARs. The parameters of the classical and compacted 400 kV transmission line are entered into the model in the example of 400 kV line Tuzla 4 - Višegrad, and Single Line to Ground Fault was simulated and compared with the actual measured data. Afterwards, lines with classical columns and pillars compacted with the lines were compared and assessed if a readjustment of distance protection on the line is necessary. The SIEMENS numerical distance relay 7SA was used.
