Converter integrated transformer
•
Transformer is in good condition after transportation.
•
The primary tap is at the same level (-5% / 0% / +5%) if this option is available. If the
network voltage is at the correct level of converter requires, just 0% tap of 3 phase
need to be shorted. The tap level should be shorted based on the actual network
voltage to match the converter requires.
•
The PT100 inside the transformer is in good condition.
Power modules
The DC link capacitors need to be reformed (re-aged) if the converter power module has
been nonoperational for more than one year. Without reforming, capacitors may get
damaged when the power module starts to operate.
•
Check the power module age.
Serial number of power module defines the week when it was manufactured. For
example, 2UBA916040009:
16: denotes manufacturing year (2016).
04: manufacturing week.
0009: running manufacturing number.
•
Regarding the instruction of reforming, refer to the documentation:
Capacitor Reforming Instructions
BCON board
Provide below information, ask for the license from MV Drives Supportline:
