What is a substation design engineer?
This role is responsible for: Design of electrical substation facilities including site and buswork layouts, grounding, foundations, controls, protection, metering and equipment drawings for internal projects.
What is 11kV substation?
11 KV Substation. Pole-Mounted Sub-Station: 1. It is a distribution sub-station placed overhead on a pole. It is the cheapest form of substation as it does not involve any building work.

What is electrical OCB?
An Oil circuit breaker aka OCB is a type of circuit breaker that uses insulating oil as a dielectric medium to quench the arc and break the circuit safely. The oil used is insulating oil used usually transformer oil that has better dielectric strength than air.
What is a substation layout diagram?
Substation layout diagrams provide scale drawings of the location of each piece of equipment in a substation, in both plan and elevation. While individual utilities may have their own format, there is a high degree of standardization of these types of drawings worldwide, for contractual and tendering purposes.
How do you build a power substation?
The basic steps a utility may perform in planning and implementing a new substation are: Conduct planning meetings for the new power substation. Perform load flow power studies. Determine the substation size and total footprint required (with equipment), including transmission right of way (ROW).
Why choose our substation design solution?
Our Substation Design solution reduces the amount of time to complete design and minimizes errors that cause rework during construction. 3D visualization of the substation increases the overall accuracy of your designs and allows for early detection of possible safety risks, such as physical clearance issues.
What is the purpose of the substation protection diagram?
These diagrams represent the protection schemes for the different substation bays by means of normalized logic structures in order to show in a structured manner the behavior of the substation protection system for any contingency. An example of such a diagram for a 115-kV line bay at a substation is shown in Figure 2.
