摘要：
A method for detecting unbalance in a 3-phase voltage signal is disclosed. The method includes determining an unbalance indicator as a value of a square of an amplitude of a positive sequence of the voltage signal; and comparing the unbalance indicator with a threshold to determine unbalance of the voltage signal.
