A protection relay is the last line of defense for electrical systems. It is a must-have tool in every building, company, or factory. But how does it work? More importantly, what can it do for you? Well, that’s what we’re about to find out.
When a protection relay detects a fault, it will trip a circuit breaker. It can protect your devices from:
You can use a protection relay to keep equipment such as motors, transformers, generators, and pumps protected.
Now that you know what it does, the next question is how it works. Well, when a device short circuits or starts to operate in an abnormal manner, the relay will immediately remove it from service. If you don’t have a protection relay, the device might cause damage or tamper with the system’s performance.
There are three distinct ways we can separate protection relays. First, you can categorize them based on the logic of use:
Then, you can categorize a protection relay based on the actuating parameter:
Also, we also have a category that’s based on application:
Finally, you can separate them based on construction:
Now, the five main things you need to consider when buying a protection relay are: durability, reliability, speed, sensitivity, and security. But if you go with a model from AlionTimer, you won’t have to worry about any of these things. You can rest assured that your relay will be durable and last you a long time.
Protection relays have many uses and functions. First, as soon as one of the components in your system starts behaving abnormally, the relay will close the circuit. It can also disconnect any parts that have stopped working. By doing so, it can minimize any potential damage the faulty part would cause your system. But that’s not all.
Protection relays can improve the performance and reliability of your entire system. They will also ensure that your system is stable, and that it doesn’t fail or stop working. Now, you might not be able to completely avoid damage due to a faulty component. But with the help of a protection relay, you can minimize the faults and help keep your systems safe.
