1. A system for measuring phase attributes of high voltage electrical lines comprising:

  • a single high voltage probe comprising a sensing element for selectively measuring current or voltage of a high voltage electrical line and developing a measured signal, and a processing circuit for detecting zero crossings of the measured signal, applying a time tag to the zero crossings, and storing samples of the measured signal and time tagged zero crossings;

    a memory for storing samples of the measured signal and time tagged zero crossings for a plurality of high voltage electrical lines; and

    a processor operatively associated with the memory for determining phase relationships between the plurality of high voltage electrical lines.
