Drawing a No Load Phasor Diagram

[Ryan Thornwell]

Hi,

I have been given a task to draw a no load phasor diagram to find values of core components of the current.

I have been given this information:-

- transformer capacity value
- delta wired
- 3 wire supply value
- P voltage
- "previous measurements for same size transformer", iron loss and no load current values.

How would I go about drawing the diagram?

In a book by John Bird I found this https://gyazo.com/1aa30c350ddf27e521159eb3b6f0c63c

Link to book - https://books.google.co.uk/books?id...KAhVCOhQKHQVIA3wQ6AEILTAC#v=onepage&q&f=false

However, this is for single phase. How would I use the equations from the book bearing in mind I have a 3 phase transformeR?
