A day in the life of a Project Engineer
My responsibilities as a project engineer changes dynamically between two disciplines during the project life cycle, one of Project Engineering and Project Management .and involves both office and site work activities.
My day as a project engineer changes everyday depending on the project phase since different skills are [...]
Transmission Lines
Transmission lines carry electric energy from one point to another in an electric power system. They can carry alternating current or direct current or a system can be a combination of both. Also, electric current can be carried by either overhead or underground lines. The main characteristics that distinguish transmission lines from distribution lines [...]
A typical power generation, transmission and distribution system has these components: Power Generation Plants, Substations, Transmission Line and Distribution systems.
Underground distribution substations are also located near to the end-users. Distribution substation transformers change the subtransmission voltage to lower levels for use by end-users. Typical distribution voltages vary from 19,920 volts to 2400 volts.
It is a large encased group of metal plates about the size of a small house with 2 sets of insulated copper wires wrapped around the plates -an input and output – to convert a very high transmission supply line voltage – maybe 44 thousand volts to a lower voltage of 2200 volts that runs [...]
Electric power transmission: Bulk transfer of electrical energy, a process in the delivery of electricity to consumers.
Transmission substation: Where you connect two or more transmission lines you would use a transmission substation.
In a very basic situation you would have two transmission lines with the same voltage. In such a situation the transmission substation contains high voltage switches that allow lines to be isolated or connected for maintenance or fault clearance.
A transmission [...]
