The EL731-20-00 is a very powerful protection relay & system designed to ensure proper operation in many different environments. The system is great for high speed operation and provides reliable protection for electrical systems and equipment.

This protection relay & system is designed for use on medium voltage power distribution systems with a maximum voltage of 6.9kV. It has an extended control range to a maximum of 20,000 operations before resetting and provides primary and back up protection for all components. The system has a built in fault and overload detection system to help reduce downtime and improve system reliability. The system also provides monitoring and display of system faults and provides full data logging capability for quick and easy troubleshooting.

The EL731-20-00 is designed to provide protection for the entire power distribution system against over-voltage, under-voltage, over-current, earth fault, short circuit, over-temperature, over-frequency, and transformer tapping protection. It can also provide current and voltage harmonics monitoring, curve differentiation, and phase mismatch monitoring.

The system operates based on a set of parameters that are programmable through the user interface. These parameters include the threshold values for current and voltage values, the delay time before operation of the relay, and the current settings for the protective elements. When any of the predefined thresholds are exceeded, the system will trigger the relay to disconnect the system. The EL731-20-00 also has an adjustable time-lag for over-load operation, allowing the user to select a time-lag before the relay cuts the power supply.

The EL731-20-00 has built-in communication ports that allow communication of system data to other components and systems, such as a supervisory control and data acquisition (SCADA) system. The system can be connected to a variety of communication networks such as GSM, Ethernet, and WLAN. The system also has built-in NFC and RFID capabilities to allow for enhanced security when communicating with external systems.

The EL731-20-00 also has advanced diagnostic capabilities. The system is capable of diagnostic checks such as relay operation speed and accuracy, capacitor discharge time, earth fault adjustment, operating power, over-current detection, under-voltage detection, and over-temperature detection.

The EL731-20-00 is the perfect solution for many applications that require high speed and reliable protection. This protection relay & system is the ideal choice for applications such as power distribution systems, high speed motor protection, machine control systems, and other similar applications.
