Safeguarding Worker from Transferred Potential in Transmission Line Work

摘要

The electrical safety in workplace should always be fault-proof in all aspects. In power transmission network, some power companies follow a practice to permanently isolate the ground wire of transmission line from the substation ground grid. This paper discusses on how the practice is risking the worker, when carrying de-energized works on a transmission line (both single circuit and double circuit), and ways to minimize the transfer of substation ground potential that rises during fault to worksite, thereby ensures the safety during the work on transmission line.
