Adjustable speed electrical power drive systems - Specification of voltage on the power interface1 Scope This part of IEC 61800 gives the guidelines for the determination of voltage on the power interface of power drive systems (PDSs). NOTE The power interface, as defined in the IEC 61800 series, is the electrical connection used for the transmission of the electrical power between the converter and the motor(s) of the PDS. The guidelines are established for the determination of the phase to phase voltages and the phase to ground voltages at the

The standard also explains how to demonstrate competence
