Introduction

In my last article I told you about Residual Current Circuit Breaker (RCCB). Today we will take a look at another important type of circuit breaker called – Earth Leakage Circuit Breaker (ELCB). An ELCB is another different class of Circuit Breakers with a specific function.

Testing faults in cables

October 5th, 2017 | 1 Comment | Posted in Electrical distribution

megaphone-blue Electrical cable faults are some of the major causes of interruptions to the smooth flow of power to the load and can also become a safety or fire hazard.

Here’s an article proposed by A.N. who sent us a lot of essays.

Introduction

The effect of a fault cable depends on the type and extent of the fault. Some cable faults reduce the amount of power reaching the load, while an open cable will completely cut off the power to the loads in the affected section.

Medium voltage DC configuration and control

September 4th, 2017 | Make a comment | Posted in Electrical distribution

The distribution is the final stage of carrying electricity from the transmission system to consumers. The distribution substations are connected with transmission lines and the voltage reduced to medium voltage through the transmission systems as shown in Fig1.
