Will 8430MPDV29 work with a grounded B phase system?

Issue:
Clarify if 8430MPDV29 will work with a grounded B phase system?
Product Line:
Supervisory Relays Type D- Phase failure for 3 Phase Monitoring.
Environment:
Phase Failure And Under-voltage Relay 8430MPDV24, 8430MPDV29, 8430MPDV20, 8430MPDV32
Cause:
Clarify if 8430MPDV29 will work with a grounded B phase system for a specific application.
Resolution:
As long as the three phases to be measured are 120 degrees apart and equal in voltage the relay should work. The relay is measuring phase to phase and doesn`t care about the grounding.
