No of disc required for 11 kV transmission line = 1 disc
Since the transmission line is 3-phase, therefore, the number of discs required for a single-pole will be 3.
Total no. of poles = 80
No of disc = 3 × 80 = 240
The stroboscopic effect is a visual phenomenon that happens when a blinking light source glows an object in movement, generating a sequence of samples. The stroboscopic effect is based on Illuminance hence it is not related to the transmission and distribution of electric power.
Magnetic Field Strength (H) gives the quantitative measure of strongness or weakness of the magnetic field.
H = B/μo
B = Magnetic Flux Density
μo = Vacuum Permeability
The magnetic Field strength at the center of circular loop carrying current I is given by
B = μoI/2r
B/μo = I/2r
H = I/2r At/m
Where r = Radius
When the field winding is connected in series with the armature winding while supplying the load then the generator is called a series generator.
As all armature, field, and load are in series they carry the same current.
IL = Ise = Ia
