it occurs???

Answer Posted / karthik

For details of the parallel operation of transformer refer
the website:
http://nptel.iitm.ac.in/courses/IIT-MADRAS/Electrical_Machines_I/pdfs/1_14.pdf

According to the literature the cause for the out of step
operation maybe due to
1)Change in voltage ratio
2)Change of polarity

Is This Answer Correct ?    3 Yes 2 No
