Dead Bus Limits
The dead bus limits define the acceptance windows for generator frequency and
voltage that is used by the CGCM-DLR unit when closing the breaker into a
dead bus. The following Configuration tab fields specify the acceptance
windows. These fields set the related tags in the Configuration table.
• Min Frequency - Tag DeadbusGenFreqLoLimit, expressed in Hertz
• Max Frequency - Tag DeadbusGenFreqHiLimit
• Min Voltage - Tag DeadbusGenV_LoLimit, expressed in volts
• Max Voltage - Tag DeadbusGenV_HiLimit
Rotation
• Generator – Specifies the generator phase rotation. Configuration table
tag GenRotABC_ACB_Select stores this value. 0 = ABC, 1 = ACB
• Bus – Specifies the bus phase rotation. Configuration table tag
BusRotABC_ACB_Select stores this value. 0 = ABC, 1 = ACB
