Soft Starter System
Variable speed drive system for Downstream industries
For industrial applications where the production processes require very high-power equipment–typically like PTA, petrochemical, air separation or carbon capture, starting the machine directly on line or with a classic starter (auto transformer, variable voltage drive, etc.) could result in serious damages to the whole installation. This is where a variable speed drive is needed, to allow the start with an inrush current not exceeding the nominal motor current.
GE Power Conversion offers a soft starter variable speed drive system based on a combination of Voltage Source Inverter (VSI) or Load Commuted Inverter (LCI) and an electrical motor.
