Prepare for the power transmission industry. Build your understanding of substations, protection, testing and commissioning — then connect with people who share your passion.
Why Read: Early-career electrical engineers interested in substations will find this news brief helpful for understanding power system expansion timelines and the typical lifecycle of high-voltage projects. Project Brief: The Federal Government (FG) of Nigeria has established a target date…
Explore an EHV transmission-line tension assembly in 3D. Learn what each fitting does, trace the mechanical load and electrical current paths, and see why four bundled conductors can form one phase.
A bigger transformer can ease one bottleneck. But what determines whether more power actually reaches the customer? The useful story in Port Harcourt is a regional capacity expansion—not the arrival of one extraordinary 635 MVA transformer. It is a chance…
Why read this? Recognising a protection-zone boundary helps an engineer interpret a protection drawing. A protection zone is the part of a system a protective device is intended to protect. In differential protection, current transformer locations define the comparison boundary.…
Why read this? Different breaker measurements answer different questions. Static contact resistance examines the closed main-contact current path. A timing test examines the timing of the switching operation. Coil-current, motor-current and motion measurements provide other forms of assessment. Illustrative comparison:…
Why read this? A transformer ratio result needs an appropriate reference. A turns ratio test checks voltage conversion against design and nameplate information. The selected tap and winding vector connections matter when interpreting the comparison. Illustrative comparison: readings for different…
Why read this? A preferred site is a planning milestone, rather than proof of commissioning. SSEN Transmission's 29 October update identifies Site 2, just over four kilometres north-east of Brechin in Angus, Scotland, as the preferred location for its proposed…
Why read this? Traction substations connect the electricity network to an electrified railway's supply. The Indian Express reports, citing National High Speed Rail Corporation Limited, that 14 traction substations are being developed for the 508-kilometre Mumbai-Ahmedabad corridor across Maharashtra and…
Why read this? This update distinguishes a substation expansion from its connected distribution works. Nilepost reports that Uganda Electricity Distribution Company Limited (UEDCL) is expanding its Greater Kampala and Wakiso network to address outages linked to rising demand. The reported…
Why read this? As a newly qualified electrical engineer, you will encounter electromagnetic interference (EMI) and electromagnetic compatibility (EMC) challenges across many industrial and infrastructure projects. This article offers a practical understanding of how specialized filters and related components—like those…
