SIPROTEC 7SA6 enables the user to set limit points (or: set points) for some
important measured and metered values. If one of these set points is reached,
exceeded or undershot, the device generates an event log. This annunciation - like all
event logs - can be allocated to LEDs and/or output relays and then transmitted via
interfaces.
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 of the currents.
• |Pdmd|>: exceeding a preset maximum average value of the active power
magnitude.
• |Qdmd|>: exceeding a preset maximum average value of the reactive power
magnitude.
• Sdmd>: exceeding a preset maximum average value of the apparent power.
• |cosϕ|<: untershooting a preset rate of the power factor
Further set points can be set if their measured and metered values have been
configured via CFC (see Section 5.3).
The exceeding or undershooting of set points is output as event log (see
Subsubsection 7.1.1.2).
