The most important requirements for electrical protection devices

There are some basic requirements that you should know before purchasing any protection device from circuit breakers, fuses, or even overloads .

The importance of electrical protection devices

Electrical protection devices are of paramount importance in protecting all electrical devices in the residential, industrial or commercial sectors.

The purpose of the protection devices is to protect the electrical loads from any possible failure resulting from the occurrence of a short circuit, overloading, voltage drop, or operating loads on voltages higher than the normal and prescribed voltage, and many other malfunctions.

It is noteworthy that the largest percentage of the faults that occur as a result of negligence or as a result of choosing an inappropriate protection element for the electrical load.

The most important requirements for electrical protection devices

Among the most important requirements that must be met in protection devices with all their functions in order to be more effective are:

selectivity or discrimination

It is the ability of the protection element to approach the fault point to separate the circuit without affecting the rest of the other electrical circuits, and among the devices that are related to selective coordination are: fuses, electrical circuit breakers, and ground leakage current circuit breakers.

Responsiveness

The speed of work of the protection element depends more estimatingly on the amount of time delay for this element, and we note that each protection device has a characteristic curve that determines the amount of time delay for it.

The benefit of the response speed of the protection devices comes so that the curve of the characteristics of the first protection device is higher than the curve of the characteristics of the protection device that comes after it, meaning that you must set the amount of time delay for the first element 0.5 seconds, while the amount of time delay for the one after it is 0.1 seconds until we make sure that the breakers are separated sub before main.

allergy

It means the lowest electric current value that can lead to the activation of the protection element.

reliability

The protection device shall be able to perform the task required of it without defect or failure under various conditions throughout its life span.

stability

This means that the protection element works stably and normally, regardless of abnormal operating conditions, so that it is not affected by errors occurring in any other circuit outside its scope of work.

Preventive coordination

Correct coordination in linking protection elements such as circuit breakers, relays, and relays (protection elements) during the occurrence of a short circuit or overload to protect the element itself to be able to return to service again after eliminating the fault with the least possible losses.
