WebFeb 16, 2024 · Half way through the sine wave we’re at 180° phase. 3/4 of the way and we’re at 270° phase. All of the values in between apply as well. Since our phase measurement changes as we move, we can recognize that phase is proportional to time. As time changes, so does the phase of a periodic signal. WebSorted by: 1. There are two common conventions of phasor rotation, which is either ABC counterclockwise or ACB counterclockwise. Any AC system strictly adhere to one of this for all their protective/metering devices.
