Basic electrical circuits and applications (wiring systems, enclosures and equipment)
The primary role of an electrician is the installation of electrical circuits and applications. In order to install any type of application, however, it is vital that from the start of your career you are able to put together basic circuitry…. Read more
Analysis of Power Distribution Systems (The impact of distributed generation)
The distribution substation is the interconnection element between the distribution system and the upstream power delivery system. At the substation the step-down (HV/MV) transformer reduces the subtransmission voltage level to an appropriate value for primary distribution lines. Different protection, switching,… Read more
Best practice in minimizing vulnerability of power systems to volcanic ashfall hazards
Electricity is the ‘life blood’ of modern society. Increasing demand for electricity has been driven by population growth and increasing use of electrically powered technologies. Electricity supply is arguably the most essential contemporary infrastructure, especially considering the dependencies of other… Read more
Complete guide to protection of medium voltage networks
This booklet aims at illustrating the basic criteria needed for good protection of machines and plants in medium voltage networks. Selection of the protection system and relays depends on and is correlated with the plant characteristics, type of industrial process… Read more
Design Guide For Overhead Distribution Systems
In older distribution systems the supply authority collects the bulk energy at 66 kV or less from the transmission substation. As indicated in Figure 1 below, there are specific voltage values used in the distribution of electrical power. These voltage values,… Read more
IEC 61850 in mine electrical distribution, automation and control systems
The IEC 61850 standard provides a mechanism for interoperability, i.e., the ability for information from Intelligent Electronic Devices (IEDs) from multiple manufacturers to be exchanged with each other; however, the standard is limited to power system components, i.e., relays, meters,… Read more
Losses in the transmission and distribution networks and ways to reduce them
When current flows in a transmission line, the characteristics exhibited are explained in terms of magnetic and electric field interaction. The phenomena that results from field interactions is represented by circuit elements or parameters. A transmission line consists of four… Read more
