A single phase transformer has the following rating : 120kVA. 2000v/100v, 60 Hz with

1000 primary turns.

Determine:

a.Secondary turns

b.The rated primary and secondary currents

2. Relevant equations

Vp/Vs = Np/Ns

3. The attempt at a solution

a. I have used the Vp/Vs = Np/Ns to work out secondary turns

1000 x 100/2000 which gave me 50 secondary turns.

b. I arent sure if I have gone about this the right way and just wanted to check.

I divided the 120000VA by the primary voltage of 2000 to give me 60A. Is this correct to do this.

Then with my 60A I put that into the Vp/Vs = Ip/Is which gave me 3A as secondary current.

Could someone please tell me if this is correct thanks
