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. motors. It applies to adjustable speed electric a.c. power drive systems with a BDM electronic power converter section connected to line-to-line voltages up to and including 1 kV a.c. 50 Hz or 60 Hz. or 1,5 kV d.c. input side. NOTE 1 - Adjustable speed electric a.c. power drive systems with a BDM electronic power converter section connected to line-to-line voltages between 1 kV a.c. and 35 kV a.c 50 Hz or 60 Hz is covered by the scope of IEC 61800-4. NOTE 2 - 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. Excluded are traction applications and electric vehicles. This part of IEC 61800 is intended to define the following aspects of an a.c. Power Drive System (PDS): - principal parts of the PDS; - ratings and performance - specifications for the environment in which the PDS is intended to be installed and operated; - other specifications which might be applicable when specifying a complete PDS. This standard provides minimum requirements, which may be used for the development of a specification between customer and manufacturer. Compliance with this standard is possible only when each topic of this standard is specified by the customer developing specifications or by product committees developing product standards. For some aspects which are covered by specific PDS product standards in the IEC 61800 series, this document provides a short introduction and reference to detailed requirements in these product standards.
