Working in office and facing problems in your electrical system? Looking for a smooth electrical system so that you can work without any issues? Then you can buy CHINT Protection Relay that are included in 3-way power supply electrical system so that any faults in the components of the electrical system can be identified quickly and the regular functioning of the system is unaffected.
Now, you must be wondering whether it is mandatory to buy protection relays for your appliances, isn’t it? So, in this article, you will know why you need protection relay for your equipment.
What is a Protection Relay?
A protection relay is a relay device intended to activate a circuit breaker when a fault is discovered. The protective relay was found more than 150 years ago.
They are little, independent gadgets that are capable of identifying discrepancies. Protective Relays can identify irregularities in the electrical circuits by continuously determining the electrical quantities that differ between normal and faulty circumstances.
The electrical quantities that could alter in faulty circumstances are voltage, current, frequency and phase angle. The protective relays receive signals from the flaws about their position, type and existence by changes in one or more of these parameters.
When a protection relay identifies a problem, it will act immediately and cut off the trip circuit for the breaker. In this manner, the circuit breaker will be open and the damaged circuit will be removed from the system.
Characteristics of Protective Relay
Below are the various characteristics of Protective relays:-
- The quick removal of the component that is acting improperly by cutting off trip circuit of the circuit breaker.
- Detach the component that is acting improperly to prevent harm or disruption with the remainder of the system’s ability to function properly.
- Detach the component that is acting improperly to stop any further failures from occurring.
- Limit the impact of the defect that is interfering with the rest of the stable system the least. Therefore, the effects of the malfunction are confined by disconnecting the defective part.
- The defect caused to the system cannot be completely removed but it will improve the performance and stability of your system.
Why is Protection Relay Used
Like we mentioned above, protection relay identifies a fault in your electrical system and then protects it from that malfunction. The malfunction in the system is found by the protection relays and then immediately commences the protective measures to resolve the issue.
Protective Relays today often combine a number of different relays. These relays may control many system components and may also have a variety of actuators. A systems relay might react to particular inputs, and a combination deals with a variety of problems and situations.
Types of Protective Relay
Now-a-days, the type of electromechanical relays is used mostly on the electrical power system.
They work on the following 2 main fundamental principles:-
- Electromagnetic attraction:- Relays that work on Electromagnetic attraction work when an armature is drawn to the poles of an electromagnet. A.C. and D.C. values are used to activate these relays.
- Electromagnetic induction: – Electromagnetic induction relays are frequently used for protective relaying reasons encompassing A.C. quantities and operate on the same principle as an induction motor. As a result of their operating principle, they are not suitable with D.C. quantities.
Conclusion
A malfunction or unfavorable change in variables such as voltage and current among others may cause the electrical system to fail and cause other issues.
Protective Relays identifies the fault in the system and resolve the issue so that the system works smoothly. Though the malfunction is not completely removed from the system but it guarantees that such the malfunction doesn’t affect the system again.
If you are looking to buy a high quality protection relay, you can buy CHINT Protection Relay which ensures that no fault enters your system and makes it run smoothly without any issues.
