R1+R2 Zs Calculator
– VERIFY R1+R2 & Zs –
Have multiple R1+R2 calculations to complete? It’s faster with the app.
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
- Ze
App Reviews
Don’t take our word for it – here’s what other app users say:
Simple helpful app to make calculations faultless.
Great little app. Very handy.
Simple, slightly faster than a calculator time is in short supply nowadays.
Great app and very useful.
Calculate 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.
Calculate Ze
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
