We provide 21Z Fault Impedance Calculator online (apkid: com.udayvank.faultimpedance) in order to run this application in our online Android emulator.
Description:
Run this app named 21Z Fault Impedance Calculator using MyAndroid.
You can do it using our Android online emulator.
Accurate fault location reduces operating costs by avoiding lengthy and expensive patrols.
Accurate fault location expedites repairs and restoration of lines, ultimately reducing revenue loss caused by outages.
Several methods of estimating fault location are presently used in the field:
DFR and short circuit data match
Traveling wave methods
Impedance-based methods
> One-ended methods without using source impedance data
(simple reactance, Takagi)
> One-ended methods using source impedance data
Two-ended methods
This app uses simple reactance method for fault location calculation using relay fault record parameters.
It is to note that fault location determination accuracy depends upon various parameters including fault type, fault resistance, source impedance, homogeneousness of line, remote feed etc.
So, in all cases fault impedance based fault locator methods can not serve accurate result.
However, it can be used as approximation\assumption.
