Master’s in Digital Substations (IEC 61850)
Online master's programme of 1,900 hours in digital substations (IEC 61850), 12 modules covering the IEC 61850 data model, SCL engineering, process bus, digital protection and control, substation networks, cybersecurity, testing and commissioning, asset monitoring and new architectures, with an assigned technical tutor.
Master’s in Digital Substations (IEC 61850) — studying from South Africa
Energy is a defining sector in South Africa, with Eskom operating the bulk of the national generation and transmission network and independent power producers increasingly contributing renewable capacity. Grid modernisation, renewable integration and distribution management create steady demand for engineers. The National Energy Regulator of South Africa oversees electricity regulation, while municipalities manage local distribution. Energy engineers typically work on generation, transmission, protection and system planning.
Fees for South Africa: R 110 000 (South African rand), with instalments and employer sponsorship available.

Questions from South Africa
Which South African bodies regulate energy and networks engineers, and would SEIUM count?
Energy engineers in South Africa are registered through ECSA, and the electricity sector is regulated by NERSA. Utilities and networks often require registered professionals for certain work. SEIUM is a private online institute, and its qualifications are not official state degrees or accredited by a national body. Recognition is for employers and the relevant body to decide, so verify this before enrolling.
Will this qualification help me find work with energy or network employers in South Africa?
South Africa's energy sector includes Eskom, municipalities, independent power producers and grid-related firms, which typically hire registered and experienced engineers. A private online qualification may support your application but does not guarantee a role. Check with target employers how they view it, and combine it with practical experience where possible.
How do I manage the workload, and can I get help with fees?
The programme is fully online and taught in English, so you need good English, and no student visa is needed to study from home. Master's programmes are 1,900 hours, postgraduate diplomas 800 hours and specialist courses 300 hours, with an assigned technical tutor and a final project. Fees are payable in instalments, and employer sponsorship may be possible, so ask your employer whether they would support the cost.
