Reference excerpt

The Karuma–Kawanda High Voltage Power Line is a high voltage electricity power line, under construction, connecting the high voltage substation at Karuma Hydroelectric Power Station, in the Western Region of Uganda, to another high voltage substation at Kawanda, in the Central Region of Uganda.

Location The 400 kilo Volt power line starts at the 400kV substation a Karuma Hydroelectric Power Station, Kiryandongo District, in Uganda's Western Region, approximately 260 kilometres (162 mi), by road, north of Kampala, the capital and largest city in the country. The power line travels in a general south-easterly direction to end at another 440kV substation owned by Uganda Electricity Transmission Company Limited (UETCL), located at Kawanda, in Wakiso District, a total distance of about 264 kilometres (164 mi).

Overview The power line is being developed in tandem with the 600 MW Karuma Hydroelectric Power Station, whose output is expected to be consumed locally and the balance sold regionally, with Burundi, Rwanda and DR Congo as potential customers. This power line is planned to evacuate the power from Karuma to Kawanda, where it can be distributed to the regional customers.

Associated power lines Two other high voltage power lines are under construction to evacuate power from Karuma: (a) The 60 kilometres (37 mi), 400kV Karuma–Olwiyo High Voltage Power Line, connects Karuma Power Station to a substation in Olwiyo, Nwoya District, for onward transmission to Pakwach, Nebbi, Paidha, Arua, Koboko, Yumbe and Moyo. and (b) The 80 kilometres (50 mi) 132 kV Karuma–Lira High Voltage Power Line, which connects Karuma to Lira.

Construction Sinohydro Corporation Limited, the main contractor for the construction of Karuma Power Station is the contractor on this project. The supervising engineering company is "Intec Gopa International Energy Consultants". The budgeted cost of construction, including the cost of the other two energy evacuation lines from Karuma is approximately US$290 million. Funding was obtained from the Exim Bank of China. Construction began in 2015, with commercial commissioning expected in 2018. In March 2020, the Daily Monitor reported that, as of that date, 617 steel high voltage towers had been completed, out of a total of 639 needed to complete the line. That left 22 towers to completion, including 5 in Wakiso District, 4 in Luweero District, 2 in Nakasongola District and 11 in Kiryandongo District. Therefore, at that time, the line was 96.5 percent complete, with 3.5 percent uncompleted. Commissioning of the transmission line is scheduled for June 2020.

Worked examples

Example 1 — a first encounter with Karuma–Kawanda High Voltage Power Line

Start with the simplest possible case. Write down what Karuma–Kawanda High Voltage Power Line claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Karuma–Kawanda High Voltage Power Line before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Karuma–Kawanda High Voltage Power Line ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Karuma–Kawanda High Voltage Power Line

In research: Karuma–Kawanda High Voltage Power Line appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Karuma–Kawanda High Voltage Power Line in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Karuma–Kawanda High Voltage Power Line is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy in Uganda, Energy infrastructure in Africa, High-voltage transmission lines in Uganda, so understanding it makes those chapters shorter.
In everyday life: Look for Karuma–Kawanda High Voltage Power Line outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
