Hi Experts,
I'm trying to analyze set-up of transformer in IS-U DM. I have following questions:
1) To calculate Billing Factor CT/PT ratio and Transformation ratio are used. What is the significance of both these ratios? How they are practically available in transmission of electricity?If transformation ratio is there, will it not suffice the calculation of billing ratio alone?
2) Is only technical installation of transformer sufficient for calculating billing ratio?
3) What will happen if there are 2 CT & 2 PT transformers available. How the billing ratio is calculated?
