Abstract
A system for measuring phase attributes of high voltage electrical lines comprises a single high voltage probe. The probe comprises a sensing element for selectively measuring voltage of a high voltage electrical line. A processing circuit detects zero crossings of the measured voltage, applies a time tag to the zero crossings, and stores samples of the amplitude and time tagged zero crossings. A memory stores samples of the amplitude and time tagged zero crossings for a plurality of high voltage electrical lines. A processor is operatively associated with the memory for determining phase relationships between the plurality of high voltage electrical lines.
