Scope
This part of GB 12668 specifies the electromagnetic compatibility (EMC) requirements for electrical drive systems (PDS). The definition of PDS is described in Clause 3.1. Here, electrical drive systems include speed-regulated AC motor drives and DC motor drives. These EMC requirements are specified for PDS with an AC input and/or output voltage (line voltage) effective value below 35 kV.
The PDS covered in this part refer to those installed in residential, commercial, and industrial premises, but traction applications and electric vehicles are not included. PDS can be connected to industrial or public distribution networks. Industrial networks are powered by a dedicated distribution transformer, which is usually located within or near industrial areas and supplies power only to industrial users. Industrial networks can also be powered by their own generating equipment. Additionally, PDS can be directly connected to low-voltage public grids, which also supply power to civilian users, where the neutral wire is typically grounded.
This part relates to EMC and covers a range of PDS types, from a few hundred watts to hundreds of megawatts. PDS are often integrated into larger systems. Aspects related to systems are not addressed in this part, but guidance is provided in the informative appendices.
These requirements are selected to ensure adequate electromagnetic compatibility (EMC) for PDS in residential, commercial, and industrial premises. However, these requirements cannot cover extremely rare extreme scenarios. Changes in the EMC performance of PDS due to fault conditions are not considered.
The purpose of this part is to determine the limits and test methods for PDS based on their intended use. This part includes requirements for immunity to disturbances and for preventing electromagnetic emissions.
Note 1: Electromagnetic emissions may cause interference with other electronic devices (such as radio receivers, measuremen
