Among all the types of protection relays & systems, EL731-14-00 is widely used due to its excellent performances. It is a overcurrent device with 10 to 14 characteristicts. EL731-14-00 is suitable for a multitude of power system applications and protection schemes. It is suitable for directional and non-directional protection in overhead lines, cables, power transformers, motors, generators, feeders, busbars, and two isolated parts of the same system.

The working principle of EL731-14-00 protection relays & systems is based on the principle of overcurrent. It is designed to detect abnormalities and the overcurrent conditions which occur in the system. The device works by measuring the current in the system and comparing it to a set of pre-set values. When the measured current exceeds these threshold values, the device will activate a signal to be sent to the corresponding equipment. Depending on the application, the signal can be used to trip the circuit breaker or to trigger alarms for manual intervention.

The EL731-14-00 can be adapted for range, time, and current limit settings. These settings will ensure that the device will operate correctly in different environments, protecting the power systems from damage due to overvoltage and other hazardous conditions. It also provides protection for reactive power flows, active power flows, and phase-to-ground fault detection.

EL731-14-00 is programmed by means of a programmable logic controller (PLC). This device is essentially a miniature computer that is designed to interface with the relay and enable it to respond to signals quickly and accurately. The programming of the PLC can be modified depending on the application, allowing the device to be optimized to suit different requirements. In addition, the PLC can also be used to monitor the performance of the relay, enabling it to be adjusted or replaced when necessary.

The most important aspect of EL731-14-00 protection relays & systems is its ability to detect faults quickly and accurately. This ensures that the system is protected from damage due to unexpected overcurrent and other hazardous conditions. Furthermore, the device is designed to be highly reliable and easy to maintain. It is also cost-effective, making it a preferred choice for many power system applications.
