### Adding and Subtracting Vectors

The top section of this page allows you to SUBTRACT one vector from another. (This is the action to find a phase-to-phase value from two phase-to-neutral values.) The bottom section allows you to ADD up to eight vectors. This might be an action that is needed to add (up to 8) currents in a current differential scheme. Obviously, if you need entry for less than 8 vectors then just leave the unneeded inputs blank (or put in zeroes). If more than 8 entries are needed then simply do the calculation in stages; for example if 11 entries are needed then do the first eight, then take the answer as the first entry of the next calculation and add that answer to the remaining 3 vectors to be added.

Vector Subtraction

Vector 1 magnitude : Vector 1 angle (deg) :

- Vector 2 magnitude : Vector 2 angle (deg) :

Resultant Vector magnitude : Resultant Vector angle (deg) :
