Answer the following statement(s) true (T) or false (F)
1. The synchronous motor can be implemented to correct or improve the power factor of three-phase industrial circuits, thereby reducing operating costs. 2. A squirrel-cage, or amortisseur, winding is provided for starting because the synchronous motor is not self-starting without this feature. 3. A synchronous motor must always be started as a three-phase AC induction motor with the DC field excitation connected. 4. With normal full-field excitation of a synchronous motor, the power factor has a peak value of unity, or 100%, and the AC stator current is at its highest value. 5. When starting synchronous motors of larger sizes through a starting compensator or an automatic starter, the voltage applied to the motor terminals at the instant of start is about half the value of the rated line voltage, and the starting surge of current is limited.
Confined spaces are hazardous because of the potential to trap toxic and/or explosive vapors and gases.
