<p>A data acquisition system is provided that in one example comprises a sensor electrically coupled to a data acquisition unit via a signal splitter. In use, the sensor senses one or more signals transmitted over a“live”power cable carrying, for example, 50 Hz or 60 Hz, medium voltage power. The one or more signals are then transmitted to the data acquisition unit to be stored, displayed, and/or analyzed. The data acquisition system includes a synchronizer that allows the data acquisition unit to synchronize the storage of the sensed signals to the frequency of the power transmitted over the tested power cable or system. In one embodiment, the synchronizer provides an accurate phase angle reference or trigger signal for accurate phase resolved data acquisition and testing.</p> |
