DPA53
Mode of Operation
DPA53 monitors its own
3- phase power supply.
The relay operates when all
the phases are present, the
phase sequence is correct
and each phase-phase volt-
age is above the adjusted
setpoint. The relay releases
when one phase-phase volt-
age drops below the set-
point or when the phase
sequence is incorrect.
Example 1
The relay monitors that the
power supply has the cor-
rect phase sequence and
that all phases are present.
Example 2
The relay releases in case of
interruption of one or more
phases, provided that the
regenerated voltage does
not exceed the set voltage.
