Abstract
This examines the issue of operability of PLC channels organized on 110 – 750 kV OHLs on which protective devices (PD) against lightning strikes are used in the form of overvoltage limiters and/or discharge devices. It is shown that the operation of PDs can under certain circumstances cause excessive disconnect of the line by phase-differential protection or directed protection during a short circuit on adjacent overhead lines (OHL), or passing an RP and/or EA command transferred on the PLC channel’s DTESC. A conclusion is drawn regarding the necessity of setting up special work for more detailed consideration of the specified issue.
