| Abstract: | This paper makes an improvement plan for the traditional electromagnetic type groundprotection of 110 kv and more than 110kv power transformer. Reasonagble design and simpleconnecting diagram are characteristic of this improved plan. It can overcome the shortcomingof the traditional protection and meet the requirements of ground protection of the trans-former all the better. This paper is valuable for practical engineering application to some ex-tent. |
