This thesis analyses the current situation of the power transformation measurement technique, then proposes the future development tendency of measurement technique. Technical means and technical equipment of the past can not adapt to the demands of the new situation. People must apply new knowledge and new technique to electric power substation in order to guarantee maintenance quality. A great quantity use of microcomputer protection equipment has increased the technology content of substation work, and then has brought new challenges to the field substation maintenance.%分析了变电检测设备技术的现状,并提出了检测技术的未来发展趋势.以往的技术手段、技术装备已经不能适应新形势的需要,必须应用新知识、新技术才能保障变电所的检修维护质量.微机保护装置的大量使用,意味着变电工作的科技含量正在不断的提高,给现场进行变电检修维护带来了新的挑战.
