Calculate R1 and R2 from Ze and Zs using this online R1 R2 calculator.
Use this online R1 R2 Calculator to calculate the values of R1 and R2 from given Ze and Zs. R1 represents the resistance of the circuit phase conductor, while R2 represents the resistance of the circuit earth conductor. Ze refers to the loop impedance, which is the external impedance of the earth’s fault current path to Earth. Zs represents the direct measurement, which is the total impedance of the earth’s fault current path to Earth. Calculate the measured value (R1 + R2) based on the direct measurement and loop impedance.
- R1+R2 = Measured Value
- Zs = Direct Measurement
- Ze = Loop Impedance
