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...
This means any combination resulting 200V (C200) will cause CT to saturate
i.e.
1.(20)(5A)(2 Ohm) =200 (saturate)
2.(20)(2A)(5 Ohm) =200 (saturate)
3.(20)(2A)(4 Ohm) =160 (not saturate)
Am I correct? and thank for everyone
Thank for your help. But I need further clarification on your second point(2).
If C200 means CT can supply 20 times rated current, then
1.C400 means CT can supply 40 times rated current?
or
2. C400 means CT can supply 20 times rated current with at standard burden of 4 Ohm (i.e. standard...
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
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?
