Live line maintenance, i.e. performing maintenance while power transmission lines are energized, is an efficient, economical method to ensure the reliability of electric power systems. However, live line work in Manitoba was suspended for 10 years as a result of two accidents at Manitoba Hydro, and it still has not resumed at the required capacity. In this work, an investigation into the effects of the factors associated with live line work on Direct Current (DC) transmission lines will be carried out and how the DC characteristics affect the performance of the tools used by live line workers in industry. There is suspicion that the characteristics of DC voltage may result in more hazardous working conditions than those experienced when working on the more common Alternating Current (AC). Presently, industry standards for providing worker safety do not consider the unique characteristics associated with working on DC, and are based on AC test results.

带电检修是保证电力系统运行可靠性的一种经济有效的方法。然而，由于马尼托巴水电公司发生两起事故，马尼托巴的带电作业暂停了10年，至今仍未恢复所需的能力。在这项工作中，调查与带电作业对直流（DC）输电线路的影响的因素将进行，以及DC特性如何影响带电作业工人在工业中使用的工具的性能。有人怀疑，直流电压的特点可能会导致更危险的工作条件比那些经验时，更常见的交流（AC）工作。目前，用于提供工人安全的行业标准不考虑与在DC上工作相关联的独特特性，并且基于AC测试结果。
