ABB 615 Series - Three;Single-Phase Selection Variation Examples

10.3.4.5 Three/single-phase selection variation examples
The provided rules always apply for single-phase (Phase Mode is "Single Phase") power
systems. However, for three-phase power systems (where Phase Mode is "Three Phase"),
it is required that all the phases have to be activated before the activation of the PICKUP
output. Interruption event indication requires all three phases to undershoot Voltage Int set
simultaneously, as shown in
Figure 531. When the requirement for interruption for "Three
Phase" is no longer fulfilled, variation is indicated as a dip as long as all phases are active.
In case of a single-phase interruption of Figure 535, when there is a dip indicated in
another phase but the third phase is not active, there is no variation indication pickup when
Phase Mode is "Three Phase". In this case, only the Phase Mode value "Single Phase"
results in the PICKUP_B interruption and the PICKUP_A dip.
It is also possible that there are simultaneously a dip in one phase and a swell in other
phases. The functionality of the corresponding event indication with one inactive phase is
shown in
Figure 536. Here, the "Swell + dip" variation type of Phase mode is "Single
Phase". For the selection "Three Phase" of Phase mode, no event indication or any
activation takes place due to a non-active phase.
