Three Phase Formula
Today we are sharing a super quick tip with you. The biggest error that most test takers make is when calculating a three phase formula. A three phase system must have the voltage multiplied times a factor of 1.73. (Or the square root of 3.) Without getting into heavy math or complex electrical theory; three-phase voltages must be multiplied by 1.73 at all times.
