Table 2.21
Provided that the short-circuit power of the supply S
greater than or equal to:
S SC = 3 × R SCE × U mains × I equ =
at the interface point between the user's supply and the
public system (R ).
sce
It is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution
network operator if necessary, that the equipment is
connected only to a supply with a short-circuit power S
greater than or equal to specified above.
Other power sizes can be connected to the public supply
network by consultation with the distribution network
operator.
Compliance with various system level guidelines:
The harmonic current data in the table are given in
accordance with IEC/EN 61000-3-12 with reference to the
Power Drive Systems product standard. They may be used
as the basis for calculation of the harmonic currents'
influence on the power supply system and for the
documentation of compliance with relevant regional
guidelines: IEEE 519 -1992; G5/4.
