On what factors the generating voltage depends ?
Generating voltage are (3.3kV, 6.6KV , 11KV, 13.8kV) Why so ?
Answer Posted / atreya
generating voltage= (P*B*N*Z)/ (60*A)
where,
P= no. of poles of the m/c
B= flux or excitation given
N= speed of rotation
Z= no. of conductors
A= no. of parallel paths for flow of current
(for lap wound m/c s: no. of paths= no. of poles)
(for wave wound m/c s: no. of paths= 2)

I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics. Now I have to select vector group of This transformer. To minimise 3rd harmonics, what care should I take in selection of Transformer Vecrtor group? If it is Y-Y with open Delta tertiary then what should be the rating & voltage of Tertiary Winding?

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
