    How to plot R-X diagram

    Hi, I want to plot the R-X diagram for distance relay using MATLAB. I have series of currents and voltages as follows: 1. Current, I 2. Voltage, V In order to obtain impedance, I should calculate Z, i.e.(Z=V/I) Question: 1. Should I calculate impedance,Z equal to |V|/|I| ?, or 2. Should I...

    Convert V-I excitation curve to p.u

    Hi, Can somebody tell me how to convert saturation of voltage-current excitation curve in RMS to per unit values. The only information I have are: 1. current transformer ratio, 1200:5 2. Class- C200, and 3. Data point (V-I) in rms regards

    Meaning of CT 1200/5

    Hi, When the current transformer is label 1200/5: 1. Is that means primary current that not exceed 1200A, the transformer will operate in linear region? 2.If the primary current more than 1200A, then the transformer operate in saturation region?
