Quang Anh CE CO.,LTD was the main contractor for the Xuyena Industrial Park 22kV 3200KVA substation project in Long An Province, Vietnam. The scope of the project was to build a complete 22/0.4KV 3200KVA electrical substation. This included the supply of all necessary materials and equipment such as Recloser, LTD, Circuit Breaker, Disconnecting Switches, Surge […]
Miscellaneous – Substation Design Calculations Transformer noise calculations Figure 24: The transformer core is made of laminated sheets of metal (to minimize eddy current loss). A downside to this is vibration induced by 60hertz alternating current. Noise is not only generated in core. The coil, mounting, housing, conduits, fans, pumps etc. all generate noise. Why […]

Electrical – Substation Design Calculations Protection and control analysis Figure 4: Protective relays inside the control building. Some are capable of tripping the high voltage circuit breaker in the yard. Figure 5: Several factors are considered when picking a relay. Significant ones are listed here. Why conduct protection and control analysis? Power substations contain expensive […]
System Planning Short-circuit study Figure 1: Short circuit study – oneline depicting the flow of fault current. Arrows indicate the direction of the flow. Why conduct short-circuit study? Hundreds, if not thousands, of generators are tied to the power grid. Rotating loads like induction motors are integrated as well. When a short-circuit occurs – generators pump current […]
