Introduction

Protection relays and systems perform an important role in keeping electrical systems safe. They provide safeguards for equipment from short-circuiting, over-voltage, over-heating and other faults that may affect its performance. The SE-TA12B relay is a device designed to provide a reliable, accurate and fast protection for a variety of applications. It is a versatile, programmable device that can be used for almost any voltage protection application. This article will discuss the application fields and working principle of the SE-TA12B relay.

Application Field

The SE-TA12B relay can be used for a variety of applications. In electrical distribution systems, it can be used for over-voltage, under-voltage and over-current protection. It can also be used in combination with traditional power transformers for the protection against power outages. The SE-TA12B relay can be used in medium-voltage applications as well, such as for generator protection, capacitor bank protection and generator synchronisation. Its flexibility also allows it to be used for non-electrical applications, such as HVAC, pump and fan motor protection.

Working Principle

The working principle of the SE-TA12B relay is based on a microprocessor. The microprocessor monitors the voltage and current levels of the system and triggers a trip if any of the pre-set setpoints are exceeded. Once triggered, the relay will disconnect the power to the application and send a signal to an alarm system, if present. The SE-TA12B also has a reset feature, which can be used to reset the device manually and restore power. The microprocessor also provides accurate time delays, which can be used for short-circuit protection.

Conclusion

The SE-TA12B relay is a versatile, programmable device that can be used for a variety of electrical and non-electrical protection applications. It is based on a microprocessor which monitors the system current and voltage, and triggers an alarm if the pre-set setpoints are exceeded. The relay also provides accurate time delays, which can be used for short-circuit protection. With its flexibility and dependability, the SE-TA12B relay is a reliable and versatile protection device.
