2.26.10.1Limit value monitoring
Set points can be set for the following measured and metered values:
• IL1dmd>: Exceeding a preset maximum average value in Phase L1.
• IL2dmd>: Exceeding a preset maximum average value in Phase L2.
• IL3dmd>: Exceeding a preset maximum average value in Phase L3.
• I1dmd>: Exceeding a preset maximum average value of the positive sequence system currents.
• |Pdmd|> : Exceeding a preset maximum average active power.
• |Qdmd|>: Exceeding a preset maximum average reactive power.
• |Sdmd|> : Exceeding a preset maximum average value of the apparent power.
•|cosϕ|< falling below a preset power factor.
2.26.10.2Setting Notes
Set Points for Measured Values
The settings are entered under MEASUREMENT in the sub-menu SET POINTS (MV) (MV) by overwriting the
