Why in metering Ct for ammeters ct secondary side is grounded for each Ct but not in case of CBCT (Core balance current transformer)..kindly some1 highlights the reason..is it because net flux is zero?
1385What happent when a AC motor(no break and starters ) stop and suddenly start . ? Starting current low or high?? Why?
1 2044Let's say I have 2 current carrying conductors C1 and C2 carrying currents of 5A and 10A. They are brought close to each other from a distance of infinity to a distance of 10cm away from each other - 1. What would be the values of current flowing in each conductor when (taking into account effects of interference of each conductor on the other) - a. The currents are AC b. The currents are DC c. C1 is AC and C2 is DC Please explain your answer with mathematical equations and formulas. Please specify the final numeric answer. Please make assumptions and clearly specify them.
