LRU2621

LRU2621 Application Field and Working Principle

The LRU2621 is an advanced, high performance digital relay equipped with an adjustable reverse power system. The relay is suitable for the protection of motor, transformer, generator, line and other equipment. The adjustable reverse power system of the LRU2621 is a high-precision relay which provides effective power protection. It can detect the presence of fault currents and reduce their impact on the operating system.

Application Field:

The LRU2621 is widely used in power systems. It is suitable for protecting low and medium voltage transformers, generators, motors and lines from over-current and other electrical faults. It can also be used for protection against over-voltage, under-voltage, single-phase and unbalanced load. The LRU2621 is a precise and reliable component, perfect for protecting equipment from operating problems.

Working Principle:

The LRU2621 consists of two parts, the electronic circuit and the mechanical relay. The electronic circuit consists of a voltage sensor, a current sensor and an amplifier circuit. The voltage sensor detects the variation in the supply voltage and the current sensor detects the variations in the current. The amplifier circuit amplifies the signals obtained from the voltage and current sensors. The amplified signals are then compared with the preset values and the results are used to control the mechanical relay. The mechanical relay then opens or closes the circuit depending on the results of the comparison.

The LRU2621 can also be used for measuring the power consumption of the equipment and detecting failures. In case of a fault, it can be used to shut down the system quickly in order to reduce the potential damage to the equipment. The relay also has a number of adjustable parameters, which can be used to set the sensitivity of the protection system and to adjust the time delay for the response.
