Sir,
We have a 200/1-1A CT in one substation. The classes of cores of CT are PS and PS respectively. We want to enhance the CT ratio from 200 to 400A and only one core is enough for application. There is no provision for enhancing the ratio both in primary and secondary of the CT. If we connect secondary cores in series, can the same CT be used as 400A/1A single core? What is the limitation for using 200A primary winding as 400A primary winding practically? If the cores are of 5P10 and PS classes, can the secondary cores be connected in series?
With regards,
appunni
