Current Transformer Selection Guide

 The selection of a current transformer is a simple task. There are four phases in the selection procedure - 

1. Define customer requirements: Based on the primary circuit and the metering and protection chains

2. Select from the catalog of the reference CT's the most suitable unit for the customer's need

3. If not selected from the general catalogs - the standardized CT are the most suitable unit for the customer's need

4. If none are feasible ask for feasibility studies - However, even if the special unit can be manufactured, it will nevertheless be a special make-up with all the problems which may endanger lives

Nigeria Electrical Engineering Polytechnics Syllabus as specified by UNESCO

As session begins in most Nigerian university, polytechnics and colleges of education. It is thus advisable for students to keep there self updated and alert for urgent tests and exam as might be decided by the lecturer. UNESCO in a brief UNESCO is responsible for coordinating international cooperation in education, science, culture and communication. It strengthens the ties between nations and societies, and mobilizes the wider public so that each child and citizen: • has access to quality education; a basic human right and an indispensable prerequisite for sustainable development; • may grow and live in a cultural environment rich in diversity and dialogue, where heritage serves as a bridge between generations and peoples; • can fully benefit from scientific advances; • and can enjoy full freedom of expression; the basis of democracy, development and human dignity. UNESCO's messages are of increasing importance today, in a globalized world where i...

Earthed and Unearthed System

Methods of Earthing In theory, the main power network does not have to be earthed and sometimes arguments are put forward that an unearthed network may be more reliable. In some cases this can be true, but generally an unearthed networks can be unreliable due to influence of electrical or some other factors. There are a number of ways in which an electrical power system can be operated – - Unearthed or insulated system - High impedance earthed and - Low impedance earthed arrangement Unearthed system/IT earthing system In this kind of installation, there is no formal connection to earth because there may be some high impedance connections for instrumentation e.g coil of a measuring device. Earthed vs Unearthed Electrical cable In some generators and transformers, the star point is solidly grounded. This is called Earthed Electrical system. In a three phase earthed system, phase to earth is 1.732(sqrt 3) is solidly earthed system higher than phase to phas...
