Question

1- Armature ac resistance is 1.5 times greater than armature DC resistance of synchronous machine

2- for a three phase system with neutral (3phase 4wire) we ened 3 fuses

3- Generated voltage E0 vs IF field currect represents the SCC curve of DC generator

4- short circuit currect over open circuit voltage per phase is the synchrnouhs impedance.

5- you will choose rms for AC and average for DC quantity

6-short circuit test and open circuit test are performed on rated current and voltare repectively

Answer with true or false only

thank you.

Explanation / Answer

1.true
