However, given the three phases can change independently, they are by definition orthogonal to each other. + If vector decomposition is used, it can be seen that: To obtain zero component, every phase voltage can be summed with equal weights to reveal any imbalances between phases or DC component. t (1480):1985-92. The Clarke transform converts the time domain components of a three-phase system (in abc frame) to two components in an orthogonal stationary frame (). We can express this relationship mathematically according to: The - components of the space vector can be calculated from the abc magnitudes according to: We also know (from Eqt 2, slide 8) that : Whereas vectors corresponding to xa, xb, and xc oscillate up and down the a, b, and c axes, respectively, the vectors corresponding to x and x oscillate up and down the and axes .
