ABB REG670 Applications Manual

OVPartBk: Selection of action to be taken in case the busbar voltage U
B
exceeds
Umax.
RevActPartBk: Selection of action to be taken in case Reverse Action has been
activated.
TapChgBk: Selection of action to be taken in case a Tap Changer Error has been
identified.
TapPosBk: Selection of action to be taken in case of Tap Position Error, or if the tap
changer has reached an end position.
UVBk: Selection of action to be taken in case the busbar voltage U
B
falls below
Ublock.
UVPartBk: Selection of action to be taken in case the busbar voltage U
B
is between
Ublock and Umin.
15.4.2.2 TR1ATCC or TR8ATCC Setting group
General
Operation: Switching automatic voltage control for tap changer, TR1ATCC for single
control and TR8ATCC for parallel control function On/Off.
I1Base: Base current in primary Ampere for the HV-side of the transformer.
I2Base: Base current in primary Ampere for the LV-side of the transformer.
UBase: Base voltage in primary kV for the LV-side of the transformer.
MeasMode: Selection of single phase, or phase-phase, or positive sequence quantity
to be used for voltage and current measurement on the LV-side. The involved phases
are also selected. Thus, single phase as well as phase-phase or three-phase feeding on
the LV-side is possible but it is commonly selected for current and voltage.
Q1, Q2 and Q3: Mvar value of a capacitor bank or reactor that is connected between
the power transformer and the CT, such that the current of the capacitor bank (reactor)
needs to be compensated for in the calculation of circulating currents. There are three
independent settings Q1, Q2 and Q3 in order to make possible switching of three steps
in a capacitor bank in one bay.
TotalBlock: When this setting is On the voltage control function, TR1ATCC for single
control and TR8ATCC for parallel control, is totally blocked for manual as well as
automatic control.
AutoBlock: When this setting is On the voltage control function, TR1ATCC for single
control and TR8ATCC for parallel control, is blocked for automatic control.
