PowerGrid SolutionsHealthcareAviationSkills DevelopmentNigeria, Africa’s largest power privatization market reflects what’s possible through a determined effort to bring private sector participation in the power sector. The privatization strategy appears to be working in Nigeria after the government successfully sold 5 power generation and 11 distribution companies in 2014. The ongoing reforms in Africa’s largest economy also usher in Greenfield projects. GE is working closely with the new owners of privatized assets to ramp up power production. Independent Power projects in Nigeria that GE is currently working with include Ogorode, Benin, Omotosho, Olorunsogo and Alaoji Power Plants – all with a combined GE-enabled installed capacity of over 4000MW. These milestones are in fulfilment of the MOU GE signed with the Federal Government, committing to help generate additional 10,000 megawatts of electricity for Nigeria over ten years. In addition, GE is prepared to support the government with a holistic end to end initiative to tackle the c...Get price

Switchgear - Wikipedia

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along withGet price

Maintenance and troubleshooting guidelines for a typical high

Maintenance RequirementsPreparation Before MaintenanceMaintenance ProcedureSwitchgear SparesLubrication of Operating MechanismsTroubleshooting GuideMaintenance covers a wide range of activities, all of which are required to keep the switchgear in ready condition at all times to enable it perform its functions satisfactorily. The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance. The latter components are likely to need periodic inspection and servicing only, to ensure that the equipment is free from dirt, dampness and deterioration, such as corrosion of metal work and...Get price
