Design on Power Supply for the Transmission Line On-line Monitoring Equipment

To meet the increasing demands for DC power supply of monitor system in the wild, we propose to obtain energy through cooperative work between two management circuits of current transformer and lithium ion battery. The detail circuit scheme of obtaining power from main power line and lithium batter charging manager is presented, the demand of power is also solved. This paper discusses and analyzes on characteristics of design on power supply for the transmission line on-line monitoring equipment.
