Here’s an article by B.Q., one of the members of the Electrical Engineering Community. He kindly sent us this essay last week and we thought it would be nice to share it with you all! Want to be published too? Reach us by mail

By definition, “a circuit breaker is a protective device that operates automatically”. Certain fault conditions can actuate a circuit breaker resulting in a discontinuation of power supply to the relevant circuit or device.

Power Outage: safety before, during and after

Hi my fellows electrical engineers, it’s Steven Mill and today I want to deal with safety basics. So here is an article about Safety before, during and after power outage. Let me know what you think about it!

The electric power supplied to homes, factories, public places and other installations have the potential to harm the users. Even the domestic installation, which is one of the smallest, has enough current to cause death by electrocution. Other than the direct harm resulting from touching the live conductors, there are other indirect dangers such as fire hazards or accidents by moving electromechanical parts.

Today we’re glad to show you this article by A.N, our fellow member of the community. You still can send us your essays by mail. Enjoy!

Load shedding in electrical supply networks is a controlled process in which the utility company drops off part of the load in order to balance the demand and the generated capacity. This is often done whenever there is excess load on the system. In standby generators, it involves disconnecting or shedding some circuits to prevent an overload condition.

Hi everybody, it’s Steven Mill. I know it’s been a while since I haven’t published an article on the blog, but here I am. Today I want to tell you about underground cable faults and how to detect them. Ready?

detecting underground cable faults

In a power transmission and distribution system, cables serve the primary purpose of transmitting electrical energy from one point to another. A fault at any section of the cable system significantly reduces the functionality and integrity of the whole setup. This situation significantly escalates with underground cables, due to the location. With the power systems growing rapidly over the years, the number and length of cables has increased over the years…
