E.FL-LP/SO-MD-B(61) heavy-duty electric wire line protection relay is a new product developed by E.FL Technology Co., Ltd. It is widely used for the protection of high and ultra-high voltage overhead lines, substations and power plants. Its comprehensive self-diagnostic functions and a series of features make it the best choice for line protection.

The main application field of E.FL-LP/SO-MD-B(61) Heavy-Duty Electric Wire Line Protection Relay is power line protection. It can be widely used for power transmission and distribution pipelines and substations, including land power transmission lines and underwater power cables.

In addition, the E.FL-LP/SO-MD-B(61) Heavy-Duty Electric Wire Line Protection Relay can protect against overvoltage and undervoltage, phase loss, line splitting, ground wire circuit disconnection, excessive ground wire current, abnormal line current, overcurrent, and phase sequence partial tripping. It can also detect the voltage and current of various components in the electrical equipment in real-time, and monitor the operating status of the equipment and the quality of the power supply in real-time.

In terms of working principle, E.FL-LP/SO-MD-B(61) Heavy-Duty Electric Wire Line Protection Relay is based on a comparator principle which uses voltage and current inputs to detect line faults or circuit overloads and open the circuit to disconnect it. When the voltage or current is higher than the threshold set by the user, the detection circuit quickly outputs a control signal to the control unit, and the control unit then performs the corresponding action to cut off the power supply.

The protection relay adopts both analog signal processing technology and precise digital signal processing technology, which makes the unit has better sensitivity and higher accuracy. At the same time, the bi-directional rotation calculation algorithm can accurately detect the fault direction, effectively improve the accuracy of fault location, and reduce the probability of wrong tripping.

In addition, the E.FL-LP/SO-MD-B(61) Heavy-Duty Electric Wire Line Protection Relay is based on a high-performance control chip and adopts an embedded operating system, which makes it easy to monitor the operating condition of the relay and the quality of the power supply in real time. It also supports remote communication protocols such as Ethernet, hydrogen or multi-point communication, allowing users to remotely configure, debug, and monitor the relay.

In a nutshell, E.FL-LP/SO-MD-B(61) Heavy-Duty Electric Wire Line Protection Relay is a reliable, accurate and efficient product. It plays an important role in power line protection and is ideal for a variety of power transmission and distribution systems.
