Cable Impedance Calculator Zs

Earth kesalahan loop Impedansi Kalkulator .. BS 7671

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.
