English term or phrase: loop impedance
Dimensioning and selection
Safe shut-off of the smallest single-pole ground short-circuit current
Since the level of the loop impedance is decisive in determining
the level of the single-pole short-circuit current, DIN VDE 0100
Part 600 (IEC 60364-6) prescribes that the loop impedance must
be determined between the following:
• Phase conductor and the PE conductor or
• Phase conductor and PEN conductor.
This value may be determined by
• Measuring with measurement devices or
• Calculation or
• Simulation of the network in a network model.
In the "Technical specifications" section, the impedance values
for the BD2A/BD2C busbar trunking systems are listed so that it
is possible to calculate the loop impedances of a busbar
system, which contributes to the total loop impedance.
With the aid of the loop impedance of the entire busbar trunking
system it is easy to calculate the smallest expected single-pole
short-circuit current.
c = Voltage factor 0.95
Un = Voltage between the phase conductors
Zk = Short-circuit impedance
Ikl min =
c × Un
3 × Zk
