Chapter 2 Product Information
frequency, KM3 is closed and KM1 and KM2 are open.
The system consists of a high-voltage cabinet, an automatic bypass cabinet, a high-voltage
AC drive and a high-voltage motor, of which the automatic bypass cabinet and the high-voltage
AC drive are provided by Veichi Electric (the high-voltage cabinet is already available in the
original system).
