THE LOW COST METHOD OF MEASUREMENTS SYNCHRONIZATION IN THE LOW-VOLTAGE NETWORK ON FREQUENCY AND THE VOLTAGE PHASE

Abstract:
The work proposes and analyses a new low cost method of measurements synchronization in electric low-voltage networks. The method is based on a finding the maximum factor of correlation among (between) the graphs of frequencies variations. The efficiency of the method has been tested on acting 0.4 kV feeders by field synchronous measurements. Timing accuracy of measurements’ synchronization for low-voltage networks via the suggested method is not worse than 3.5-70 µs.
