Protection Relays & Systems

The SE-135-10 protection relay and system are designed for low-voltage overhead electrical lines. The relay is responsible for managing the protective overload system and providing overall protection for the transmission line. The SE-135-10 protection relay system includes a variety of elements including a disconnector, lightning arrester, lockout mechanism, switching contact, overcurrent relay and fuses. Together, these components provide an important safety feature, while also increasing the efficiency of the electrical transmission system.

Application Principles

The SE-135-10 protection relay system utilizes various functions such as instantaneous overcurrent protection, ground fault protection, ac protection, shunt trip, and lockout. These functions are designed to provide immediate electrical protection if a fault is detected in the electrical transmission line. Instantaneous overcurrent protection is used to protect the electrical transmission system by removing power supply as soon as an overcurrent condition is detected. Additionally, ground fault protection is a function of the system that provides fast and accurate grounding of the conductor by activating if a ground fault is detected. The ac protection function is used to detect voltage irregularities caused by phase unbalances, while the shunt trip function is used to provide protection against short-circuit conditions. The lockout mechanism is designed to disconnect the electrical transmission system in the event of a fault.

Working Principle of SE-135-10

The working principle of SE-135-10 protection relay system revolves around the principle of overload and short circuit protection. The system works on the principle of electrical overcurrent, detecting when the flow of electricity exceeds the allowable limits. When this happens, the system trips the transmission line, thereby cutting off the power supply from the source. This ensures that no damage is done to either the transmission line or the equipment connected to it.

In addition to overcurrent protection, the SE-135-10 system is equipped with ground fault and ac protection functions. As the name implies, ground fault protection detects when the conductor\'s electrical current drops due to a connection to ground, while ac protection is used to detect any voltage irregularity caused by a phase unbalance. When these functions detect a fault, they activate the disconnector and switch contacts in order to interrupt the electrical flow.

Finally, the system is also equipped for lockout protection. This is used to disconnect the electrical transmission line in the event of a fault, preventing any additional damage to either the transmission line or the connected equipment. This ensures that the safety of personnel is not compromised.

Conclusion

The SE-135-10 protection relay and system are designed for use in low-voltage overhead electrical lines. The system utilizes various functions such as instantaneous overcurrent protection and ground fault protection to provide safety and protection for the transmission lines. The system is also equipped with ac protection, shunt trip, and lockout mechanisms to ensure the overall safety of the electrical transmission system. By utilizing these functions and mechanisms, the SE-135-10 relay and system are able to provide comprehensive protection for both the transmission line and equipment attached to it.
