1 Scope
This part of IEC 61800 applies to adjustable speed electric a.c. power drive systems , which include semiconductor power conversion and the means for their control, protection, monitoring, measurement and the a.c. motor s.
It applies to adjustable speed electric power drive systems intended to feed a.c. motors from a BDM connected to line-to-line voltages up to and including 1 kV a.c. 50 Hz or 60 Hz and/or voltages up to and including 1,5 kV d.c. input side.
NOTE 1 Adjustable speed electric a.c. power drive systems intended to feed a.c. motors, and with rated converter input voltages above 1 000 V a.c. are covered by IEC 61800‑4.
NOTE 2 Adjustable speed electric d.c. power drive systems intended to feed d.c. motors are covered by IEC 61800‑1.
NOTE 3 For adjustable speed electric a.c. power drive systems having series-connected electronic power converter sections, the line-to-line voltage is the sum of the series connected input voltages.
Traction applications and electric vehicles are excluded from the scope of this standard.
This part of IEC 61800 is intended to define the follow...
