The number of turns of primary and secondary
SpletNp is the number of turns on the primary coil Ns is the number of turn on the secondary coil In a step-up transformer, Vs > Vp. In a step-down transformer, Vs < Vp. Example A mains … SpletThe addition of extra turns to the secondary winding as shown in Fig. 14.1 allows a change in output voltage from, say, V 2 to V 2 +ΔV as the primary to secondary turns ratio is decreased. In transmission systems the control of the voltage may be achieved by varying the transformer ratios or the effective number of turns in service by using taps.
