The utility model discloses a power transmission and distribution line electrical parameter online measuring device comprising a plurality of measuring units respectively communicating with a main station system through a data concentrator; the measuring units can carry out time synchronization through a clock synchronization unit; the measuring units use a one-time CT (current transformer) and a one-time PT (potential transformer) to collect synchronization phasor data of corresponding measuring points at a same time point at a set time interval; the measuring units also use a measuring range switching circuit to connect with a measuring current sensor and a protection current sensor; the measuring range switching circuit can still record corresponding waveforms when the line is in failure, and the measuring units can send the collected data to the main station system through the data concentrator. The power transmission and distribution line electrical parameter online measuring device uses the synchronization phasor measure terminal DPMU, specially belonging to the distribution system, to improve distribution network data acquisition realtimeness and accuracy.
