Its function is to lower the voltage levels for distribution 1st level purposes. iii) Distribution Transformers – located at small distribution substation. It lowers the voltage levels for 2nd level distribution purposes. g. Potential Transformer (PT) , Current Transformer (CT) 2 EEEB344 Electromechanical Devices Chapter 2 2. The Ideal Transformer 1. Definition – a lossless device with an input winding and an output winding. 2. Figures below show an ideal transformer and schematic symbols of a transformer.

L = vBl sin θcd out of the page 4. Segment da same as segment bc, v x B is perpendicular to l. Thus, eda = 0 Total induced voltage on the loop eind = eba + ecb + edc + ead = vBl sin θab + vBl sin θcd = 2 vBL sinθ since θab = 180º - θcd and sin θ = sin (180º - θ ) Alternative way to express eind: If the loop is rotating at a constant angular velocity ω, then the angle θ of the loop will increase linearly with time. θ = ωt also, the tangential velocity v of the edges of the loop is: v= r ω where r is the radius from axis of rotation out to the edge of the loop and ω is the angular velocity of the loop.

In the figure above, the net magnetomotive force is Fnet = NPiP - NSiS This net magnetomotive force must produce the net flux in the core, so Fnet = NPiP - NSiS = φ R Where R is the reluctance of the core. The relationship between primary and secondary current is approx Fnet = NPiP - NSiS ≈ 0 as long as the core is unsaturated. Thus, NPiP ≈ NSiS iP N S 1 = = iS N P a In order for the magnetomotive force to be nearly zero, current must flow into one dotted end and out of the other dotted end. As a conclusion, the major differences between an ideal and real transformer are as follows: a) An ideal transformer’s core does not have any hysteresis and eddy current losses.
