A measurement system for the testing of transmission lines was designed and implemented, which greatly reduced the testing time,avoided the arrangement of cables,and hence enhanced the effi-ciency of the test.The measurement system,consisting of a center station,a current acquisition and trans-mitting node,a voltage acquisition and transmitting node,etc.,is based on wireless communication.A high-speed wireless bridge working at 2.4GHz together with a clock synchronization module based on the IEEE1588 communicating protocol was employed for the communication and time synchronization.The da-ta storage,waveform display,data analysis,automatic report generation and other functions have been achieved in the measurement system.A practical test was done at a 500 kV substation in Jiangsu Province of China,which proves the validity and effectiveness of the measurement system.
