Description

R1+R2 ZS / ZE CALCULATIONS

Easily calculate the earth loop impedance (Zs) from the R1+R2 and Ze values or calculate the R1+R2 value from the Zs / Ze values.

A handy app for checking & verifying measured R1+R2 values or for calculating a value (Zs, R1+R2) from the other two known values.

While this app can calculate Ze, Ze values should only be obtained by direct measurement or by inquiry, not calculated. It is best practice to directly measure R1+R2 and Zs values.

- Zs, Ze and R1+R2 calculations with instant results!

Features

  • Zs
  • R1+R2

R1+R2 FROM Zs

To calculate R1+R2 from Zs enter your measured Zs and measured Ze values, then hit “Calculate”.

Calculating R1+R2 or Zs is a very simple calculation but if you have multiple calculations to do then that’s where this app can speed up the process.

Calculates:

  • R1+R2.
  • Zs (Earth Loop Impedance).
  • Ze (External Earth Loop Impedance) – not recommended to calculate.

Enter any two values to calculate the other!


To Calculate R1+R2:

R1+R2 = Zs – Ze

Calculate Zs

Zs FROM R1+R2

To calculate Zs enter your measured Zs and measured R1+R1 values.


To Calculate Zs:

Zs = Ze + R1+R2


Max Zs

For maximum Zs values see our Max Zs Values App.

Ze CALCULATIONS

Ze should not be calculated, Ze should only be obtained by direct measurement with the appropriate test equipment and approved procedures.

Saves Time

R1+R2 Zs CALCULATIONS

If you have multiple R1+R2 or Zs calculations to complete this app can help by saving time, for example, when calculating R1+R1 enter your Ze and Zs values and calculate, then for the next calculation just update the Zs value and calculate again.

  • Quick n Easy
  • Saves Time
  • Calculate Zs from R1+R2 and Ze
  • Calculate R1+R2 from Zs and Ze

Enter any two values to calculate the remaining value.

FAQ's

FREQUENTLY ASKED QUESTIONS

What is Zs?

Zs is the earth loop impedance of an electrical circuit.

What is Ze?

Ze is the earth loop impedance external to the electrical installation.

How to Calculate R1+R2

To calculate R1+R2 we can use this formula, Zs – Ze = R1+R2

How to Calculate Zs

To calculate Zs we can use this formula, Ze + R1+R2 = Zs
