2-10 Parameter Descriptions
7000-TD002A-EN-P – September 2007
Bus Transient Level [BusTransient Lvl]
Linear Number: 767
Minimum Value: 0.000 pu
Maximum Value: 32.767 pu
Access Level: Service
Read/Write: Read Only
The bus transient algorithm has been improved to reduce self-induced nuisance trips caused by fast dc
current, pulse number and firing angle changes. The rectifier temporarily disables the bus transient when
it determines that it may generate a transient in the input filter. This can be compared to Bus Tran Trip
#684 to determine when the transient occurs.
