Course overview:
High voltage substation design is a complex engineering activity that embraces a wide variety of disciplines. This comprehensive overview brings these disciplines together to give you an interactive guide to high voltage, air or gas insulated substation design.
The course considers all aspects of the design process, including a detailed review of network topology, the interaction of the different elements of substation design and operation, an introduction to substation equipment and its function, and an explanation of the many interfaces between engineers, architects and other specialists that are required for substation construction.
The attendees will be guided through a step-by-step study of the substation design and construction and maintenance processes. All phases for MV/LV, MV/MV & MV/HV substation design, from initial site review, selection, grounding design, all the way to substation start-up and commissioning will be covered. Moreover, regular Substation maintenance can limit exposure to the risk of significant plant downtime by preventing or identifying potential issues before problems occur.
Exercises, group discussions, pictures and videos will be used to further demonstration of concepts.
Key benefit of attending this event includes:
- Have overall understanding of substation technology
- Understand the concept of substation design practices and equipment selection
- Acquire in-depth knowledge of substation earthing design, determination of step potential, touch potential, grid potential rise etc.

IN HOUSE AND ONLINE TRAINING
While both In-House and Online training can present with cost-effectiveness and time-efficacy, there are some very specific differences between in-house courses and those based online.
The demand for additional courses by individuals or groups of people is increasing. Still, it depends entirely on the preferences of a person what type of training he or she wants to receive. Online courses and in-house training carry some similarities but they are considered to exhibit some very pivotal differences too. Despite that, both types of learning can be really beneficial for attendees.
