Magnetic Field Due to a Long Current-Carrying Conductor

by

Suppose there is a current-carrying conductor. This conductor carries a current of I amperes. Now, we shall consider a small length dx of the conductor. Also, we shall consider a point P as the observation point. The position vector of that point from the conductor segment dx is r. This means the straight distance between … Read more

Working of Nuclear Power Plant – A Complete Introduction

by

The storage of fossil fuel like coal is going to be finished in near future. So, we need an alternative source of energy for large scale electric energy generation. This is where nuclear energy comes into picture. Many developed and developing countries have found the tremendous capability of electricity generation of nuclear power. Theory of … Read more

Hydroelectric Power Plants – A Complete Introduction

by

Hydroelectric power is the oldest and cheapest method of large-scale electricity generation. Remarkably, it runs entirely on water. Furthermore, it produces zero direct emissions. Best of all, it costs almost nothing to operate once built. In addition to power generation, most hydro projects also control floods, store irrigation water, and support navigation — all simultaneously. … Read more

Winding Resistance Measurement Test of a Power Transformer

by

In the winding resistance measurement test of a power transformer, we simply use either the ammeter-voltmeter method or the Kelvin Double Bridge method. Actually, we inject DC current to the winding of the transformer. Additionally, we measure the voltage drop across it. Then we determine the resistance value of the winding by dividing the voltage … Read more

What is an Electrical Fault? A Complete Explanation

by

In this article, we will discuss the electrical faults that normally occur in a power system. A short-circuit fault means the connection between two conductive parts of the system through a low-impedance path, where these two parts are at different voltage levels. Due to the low impedance of the path, as well as the voltage … Read more

Protection Zones and Overlapping Zones in Power Systems

by

The primary objective of a power system protection scheme is to isolate only the faulty section of the network while keeping the healthy portions in service. This approach improves system reliability and ensures continuity of power supply to consumers. Whenever a fault occurs in any part of a power system, it is desirable to disconnect … Read more
