3.1.6.45 Redundant cell rank (option U13)
This option permits the failure of one cell per converter phase, without the converter identifying
a fault or losing its full output capacity.
3.1.6.46 Sinusodial filter (option Y15)
This option allows line motors or motors with insulation systems that are not compatible with
converters to be operated with speed control. The sine-wave filter supplies the motors with
virtually sinusoidal motor currents and voltages, which means that line motors can be used.
These filters are generally required when the output cable is longer than 2.2 km. With such
lengths, harmonics and sidebands in the switching frequency can produce a line frequency
that may cause overvoltage in the transmission line at the motor terminals.-++
The sine-wave filter essentially contains an L-C filter; these components are installed in
transition cabinets. The reactors are usually custom-configured.
