Detailed Description
Example 1
As shown in fig. 1, the system for monitoring line loss of a 10kv power distribution network is provided, a current monitoring device 1 collects line power data information and sends the line power data information to a receiver through a wireless micro-power consumption channel, and the receiver transmits the line power data information to a remote monitoring master station through gprs.
As shown in fig. 2 and 3, the current monitoring device 1 in this embodiment includes an open-close type current transformer, and a data acquisition and processing module, a communication module, and a power module that are built in the open-close type current transformer.
