High voltage station – Design, construction and commissioning process
The development of a high-voltage (HV) substation is a massive multidisciplinary undertaking. Recent trends in utilities have heavily favored sourcing the design and construction of HV stations through EPC (Engineering, Procurement, and Construction) or turnkey contracts. Regardless of the procurement… Read more

Electric Motor
Synchronous Motor Construction
Synchronous motors convert electrical power to mechanical power and synchronous generators convert mechanical power to electrical power; and synchronous condensers supply only reactive power to stabilize system voltages. Synchronous motors, generators, and condensers perform similarly, except for a heavy cage winding on the… Read more
