The most common methods of measuring the resistance of an earth electrode

The most common methods of measuring the resistance of an earth electrode

When an earth electrode system has been designed and installed, it is usually necessary to measure and confirm the earth resistance between the electrode and “true Earth”. The most commonly… Read more EEP – Electrical Engineering Portal Jobs from Indeed What: Where: jobs by »

Three-phase Y and Delta Configurations | Polyphase AC Circuits

Initially we explored the idea of three-phase power systems by connecting three voltage sources together in what is commonly known as the “Y” (or “star”) configuration. This configuration of voltage sources is characterized by a common connection point joining one side of each source. (Figure below) Three-phase “Y” connection has three voltage sources connected to a common point. If we draw a... »

Vector Group of Transformer

Vector Group of Transformer Introduction: Three phase transformer consists of three sets of primary windings, one for each phase, and three sets of secondary windings wound on the same iron core. Separate single-phase transformers can be used and externally interconnected to yield the same results as a 3-phase unit. The primary windings are connected in one of several ways. The two most common con... »

Control of Synchronous Generators with Droop and Cross-Current Compensation.

Control of Synchronous Generators with Droop and Cross-Current Compensation. Details   Written by Stefanos Spanopoulos, MIET The excitation of a synchronous generator is usually done by an AVR (Automatic Voltage Regulator) that uses generator voltage and/or current as inputs in order to control its output to a pre-set value. AVRs include different control modes to optimise performance dependi... »

The Mind Guide – By Tamunofiniarisa Brown The Mind Guide: To destroy every inner negative attitudes and energies, and establishing pragmatic forms of your inherent great potentials This is because some individual had accepted poverty, and believed they will never be rich; others had accepted defeat in life, and lay blames on their surroundings, friends, and families, instead of blaming it on... »

Project Management Triple Constraints on the GOLDEN TRIANGLE

Project Scope Definition(The Scope Triangle)-2

Project Scope Definition(The Scope Triangle) -2   Scope Verification It is pertinent to note that the project involves changes, and this necessitates scope management process, which consist of Scope Planning, Scope Definition, Creating the WBS, Scope Verification and Scope Control (Wysocki, 2009, p.593). However, these processes cannot be done totally in isolation; they complement one another... »

task dependencies

Project Scope Definition(The Scope Triangle)

Project Scope Definition(The Scope Triangle) Every project, no matter how small, has tasks and activities based upon the requirements. Therefore, there is need to breakdown these activities into tasks until further breakdown is impossible or unnecessary for feasibility in managing the objects. This breakdown will help greatly in estimating the cost and duration of the entire project. Reference to ... »
