Variable speed electric drive with increased human protection for unearthed neutral systems
For human safety, electrical systems are required to have neutral wire connected to earth. In some applications (ships, aircrafts, and underground operations) neutral cannot be earthed, causing problems of undetected faults and dangerous potentials. This research has developed a high quality variable speed drive for electric motors, which also provides increased safety and instant fault detection in unearthed neutral systems.
Typical land-based variable speed drive offer speed control and high energy efficiency. However, they:
The developed drive provides the top-level control accuracy and energy efficiency.
At the same time, it offers:
