Online calculation, sizing power line protection against indirect contact and short circuit.
Are presented formulas dimensioning of a power line, the current capacities of
cables in different conditions of installation and laying,his let-through energy in function of time
and short circuit current.
Are presented formulas for the calculation of the voltage drop along a line with the load and the tables
of 'unitary impedance and reactance of the cables.
There is also this online calculation for a three-phase power line and the voltage drop that
presents its ends . Are implemented algorithms for the verification of security
of the line and the algorithms for calculating the maximum length of the protected devices, the
protection for TT, TN and IT ... and algorithms for the calculation of short circuit current at the
end of the line).
Are presented the basic formulas for the calculation of the short circuit current along a line.
Describes the grounding systems and their components and their coordination with the protective devices
by indirect contact in HV / MV and LV (TT-TN-IT)
