1, different application scenarios: the overall positioning of broadband measuring devices is initially to provide a useful supplement for existing automatic measuring equipment, make up for the defects of existing measuring technology, and provide a new technical means for future power grid data measurement, while synchronous vector measurement is to measure synchronous vectors for 10kv distribution network lines.

2. Different functional positioning: The broadband measurement device adopts the classification processing method of low frequency, power frequency and high frequency signals in the processing mechanism of broadband measurement signals, especially the processing flow of power frequency signals is exactly the same as that of PMU, while the synchronous vector measurement device carries out low-pass filtering on the detected distribution network line signals to obtain the first signal, and then shapes the first signal to obtain the second signal.
