Weak supply networks: In weaker supply networks with a short-circuit ratio less than 8, it
is highly recommended to add an additional BAMU auxiliary measurement unit to the drive.
In such kind of networks, there is risk of unnecessary DC overvoltage tripping due to
disturbances caused by probable high voltage THD in the supply voltage. Short-circuit ratio
is defined as the supply network's apparent short-circuit power S
nominal apparent power S
(S
/ S
< 8 ).
