About Cable Impedance Calculator Zs
ELcalcZs Pro is an Electrical Calculator App,
That will calculate the Resistance of the Line Conductor and CPC (R1 + R2).
And Earth Fault Loop Impedance (Zs) for a new electrical installation.
This is Necessary for determining whether the circuits protective device
will operate within the correct time limit,
Due to the fault current generated by the
resitance of the circuit.
Works for copper cables up to 1000mm.
Allows you to select ambient temperature,
and apply correction factors for cable type.
Correction Factors listed in Help File.
Complies with BS 7671 : 2008 17th Edition.
Now has a function for calculating cable
length, when inputting R1+R2 value.
Automatically selects correction for
Cable Type / Installation and Ambient Temp.
Length given in meters.

App was much better before this update....often used it in fault finding to estimate where a cable fault might be. Pretty much useless and full of bugs and ads after update, previous version was 100 times better
