Glossary Of Terms


In a 3-phase Delta or Wye electrical distribution system, voltage imbalance refers to a condition in which the three phase voltages differ in amplitude or are displaced from their normal 120-degree phase relationship or both. Three phase loads are very sensitive to voltage imbalance. Single-phase loads are typically not sensitive to voltage imbalance. (see: Wye; Delta; Voltage; Load Balance)
