Description: To achieve higher profitability, an important objective in mining applications is to minimize the cost per ton of material moved, which leads to the use of more efficient mining machines and systems. Among open-cut excavating machines, preference is often given to electric draglines and rope shovels due to their high productivity and efficiency. Since they are the biggest machines in a mine, any efficiency improvements to their electric systems would result in significant energy savings. The dc distribution has been historically known as an effective method of power delivery. Due to recent developments in power electronics, dc distribution systems are now being seriously considered for various medium-voltage (MV) applications.
