Three-Phase Systems in Power Applications Questions

• In a Y-connected source feeding a △-connected load,
• The stator is the rotating assembly in a generator or motor.
• Power is measured in a three-phase load by using an ammeter.
• A simple three-phase generator consists of three conductive loops separated by 120°.
• A simple two-phase generator consists of two conductive loops separated by 90°, rotating in a magnetic field.
• Polyphase is characterized by two or more sinusoidal voltages, each having a different phase angle.
• In a Y-connected generator, there is a 120° difference between each line voltage and the nearest phase voltage.
• The term squirrel-cage applies to a type of three-phase ac generator.
• An alternator is an electromechanical ac generator.
• In a △-connected generator, there is a 120° difference between each line current and the nearest phase current.
• A balanced load is one in which all the impedances are equal.
