1.	Ratio error is defined as ___________(a) Ratio error =^Kn⁄R(b) Ratio error =^Kn – R⁄R(c) Ratio error = Kn – R(d) Ratio error =^1⁄RI have been asked this question by my school principal while I was bunking the class.The question is from Errors in Current Transformers topic in division Extension of Instrument Ranges of Electrical Measurements
Answer» Correct CHOICE is (b) Ratio error =^Kn – R⁄R Best explanation: Ratio error of a C.T. is DEFINED as the ratio of the magnitude of the DIFFERENCE between the nominal and ACTUAL ratio with respect to the actual ratio.
