The Port Harcourt Electricity Distribution Company (PHED) [1] is a private electric distributor that provides power for a total of 14 million people in 4 states of Nigeria including Rivers, Bayelsa, Cross River and Akwa Ibom. It first operated as a government-owned enterprise before being privatized in 2013.
Electricity generation in Nigeria began in Lagos in 1886 with the use of generators to provide 60 kW. [10] In 1923, tin miners installed a 2 MW plant on the Kwali River; six years later, the Nigerian Electricity Supply Company, a private firm, was established near Jos to manage a hydroelectric plant at Kura to power the mining industry.
The Transmission Company of Nigeria (TCN) is a federal government owned electric utility company in Nigeria established in 2005.
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
Electricity generation is the process of generating electric power from sources of primary energy.For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.
Nigeria is a federal republic in West Africa, bordering Benin in the west, Chad and Cameroon in the east, and Niger in the north. As of 2015 Nigeria has the world's 20th largest economy, worth more than $500 billion and $1 trillion in terms of nominal GDP and purchasing power parity respectively. It overtook South Africa to become Africa's ...
A "transformer bank", widely used in North America: three single-phase transformers connected to make a 3-phase transformer. The low-voltage secondary windings are attached to three or four terminals on the transformer's side. In North American residences and small businesses, the secondary is often the split-phase 120/240-volt system. The 240 ...
Since the major insulation of a live-tank current transformer is not exposed to the heat of the primary conductors, insulation life and thermal stability is improved. [1] A high-voltage current transformer may contain several cores, each with a secondary winding, for different purposes (such as metering circuits, control, or protection). [7]
