VAr Bias can be enabled or disabled. Use of VAr Bias allows coordination of the TCC300
with Autodaptive® Control devices and M
‑
6280 series Capacitor Bank Controls.

VAr Bias (Step)
Item
Description
Disable on Reverse Power
When selected, the control will disable VAr Bias
when Reverse Power is detected.
Forward Power Max 3 Phase Capacitor Bank Size
Maximum Capacitor Bank size is adjustable from 4
KVAr to 12000 KVAr.
Reverse Power Max 3 Phase Capacitor Bank Size
Maximum Capacitor Bank size is adjustable from 4
KVAr to 12000 KVAr.
Lead % Bank Size Pickup
Lower negative Var limit in percentage of the Max
Cap Bank size below which the control will increase
the upper band edge by the amount defined by VAr
Bias Voltage Step.
Lag % Bank Size Pickup
Upper positive Var limit in percentage of the Max Cap
Bank size above which the control will decrease the
lower band edge by the amount defined by VAr Bias
Voltage Step.
VAr Bias Voltage Step
Amount by which the control will increase or
decrease the Upper or Lower band edges when
there is a VAr Bias out of band situation.
Max VAr Bias Duration
Maximum allowable time in minutes the control will
bias the voltage edge.

VAr Bias (Linear)
Item
Description
Disable on Reverse Power
When selected, the control will disable VAr Bias
when Reverse Power is detected.
Current Multiplier Base Value
Adjustable from 0 to 32600.
No Voltage Reduction:
Linear Voltage Bias (-X)
The Linear Voltage Bias (-X) setting defines the
amount of voltage bias to be applied to the
Bandcenter when at 1 PU reactive current loading.
Adjustable from -72 to 0 Volts at 200 mA Reactive
Load.
Linear Voltage Bias (-X) Limit
The Linear Voltage Bias (-X) Limit, limits the total
voltage bias that can affect the control
Bandcenter.Adjustable from -5.0 to 0.0 Volts.
During Voltage Reduction:
Linear Voltage Bias (+X)
The Linear Voltage Bias (+X) setting defines the
amount of voltage bias to be applied to the
Bandcenter when at 1 PU reactive current loading.
Adjustable from 0 to 72 Volts at 200 mA Reactive
Load.
Linear Voltage Bias (+X) Limit
The Linear Voltage Bias (+X) Limit, limits the total
voltage bias that can affect the control Bandcenter.
Adjustable from 0.0 to 5.0 Volts.
