Abstract
A system for measuring phase attributes of high voltage electrical lines comprises first and second high voltage probes. Each of the probes comprises a sensing element for selectively measuring voltage of a high voltage electrical line, a processing device for detecting zero crossings of the measured voltage and applying a time tag to the zero crossings, and storing samples of the amplitude and time tagged zero crossings. A transceiver transmits storage samples. A user interface device is remote from the first and second high voltage probes and comprises a transceiver for receiving transmitted storage samples. A memory stores received samples of the time tagged zero crossings for the first and second high voltage electrical lines. A processor is operatively associated with the memory for determining phase relationships between the first and second high voltage electrical lines. A display displays the phase relationships.
