FX2ELQ1Q1SNM019 products are Intelligent digital phase-sensitive protection relays used to protect and regulate single-phase electrical networks. These products are used to protect against overloads, no current failure or earth leakage failure. The FT2ELQ1Q1SNM019 is capable of detecting fault currents up to 100 A and can be easily adjusted to the particular application. In addition, these products are also capable of providing differential protection and guidance to locate faults.

The FX2ELQ1Q1SNM019 application field is mainly in power distribution systems. The phase-sensitive current protection devices are widely used in high voltage supply networks for phase current protection, phase-to-phase fault protection, phase-to-ground fault protection, third harmonic current protection, and unbalanced current protection.

Besides the application in high voltage supply networks, the FX2ELQ1Q1SNM019 protection devices can also be used in three-phase generator remote monitoring systems, and industrial machinery and equipment protection systems. In the three-phase generator remote monitoring system, the phase-sensitive relays can monitor the phase current, three-phase balance, voltage, and time delay. In an industrial machinery and equipment protection system, these relays can protect against single-phase failure, consistent phase current unbalanced, and earth leakage current protection.

The working principle of FX2ELQ1Q1SNM019 built-in protection device is the three-phase current amplitude measurement. It measures three phases of the currents in the circuit and calculates the amplitude of the currents of three phases. If the current of one phase is too small or the phase difference exceeds the threshold, the relay will cut off the power supply of the equipment, then the machine will not be damaged due to single-phase failure or unbalanced current.

To ensure the safety of the equipment, the user can set the parameters for the detector. The user can set the relay time delay, voltage threshold, currents threshold, harmonic threshold, and earth leakage current threshold. The protective system will work according to the parameters set by the user. According to different application, the user can adjust the protection parameters to meet the system requirements.

In short, the FX2ELQ1Q1SNM019 is an intelligent phase-sensitive protection relay with various application fields. Different protection functions can be realized by setting different parameters. It has strong anti-overload capacity and can provide guidance to locate faults. Meanwhile, it is also very easy to install and convenient to use.
