Answer / bala123
Because the Form factor of AC system is 1.11,thats why the
voltage rating from the transformer was above format
Is This Answer Correct ? | 83 Yes | 10 No |
Answer / syam kumar
beacuse Tranformer output voltage is given by the equation
E = 4.44f(phi)N
so Voltages are multiples of 1.11
Is This Answer Correct ? | 32 Yes | 6 No |
Answer / vipul mali
because form factor is definded by
ff= r.m.s. value/average value
ff= 1/root 2/ 2f/ pi
ff= 1.11
so all the equipments are disigned with this value.
Is This Answer Correct ? | 20 Yes | 6 No |
Answer / eng_entropy
Because these values of voltage are the standard values
which produced by the generators.

For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
