Requirements of power supply
Declare Ssc that corresponds
to the minimum Rsce value
that satisfies the limit value.
Conforms to 61000-3-12 2004
when short-circuit power upon connection
with the commercial power is equal to
or greater than the declared Ssc.
Apply the limit value table
(Table 4) of balanced
three-phase equipment with
specified conditions.
Conforms to
61000-3-12 2004.
The expression of each item is simplified. For details, refer to the standards.
Apply the limit value table
(Table 3) of balanced
three-phase equipment.
Set the impedance of
the power supply to at
least the estimated Rsce.
Set the impedance of the
power supply to at least
1.6 times the estimated
Rsce.
Apply the limit value table
(Table 2) of equipment other
than balanced three-phase.
Is the minimum Rsce value that
satisfiesthe limit value equal to or
less than the estimated Rsce?
