RMC-131D 的工作原理

RMC-131D 通过测量三相电流的差值，当差值超过设定值时，即认为发生内部故障，发出跳闸信号。

RMC-131D 差动保护继电器

The RMC-131D is a differential current protection relay manufactured by DEIF in Denmark. It is mainly used to protect the generator from short circuit or ground fault inside the generator winding. By comparing the difference of the three-phase current, when the difference exceeds the set value, the RMC-131D will send a trip signal to cut off the fault line and protect the generator.

Main functions of RMC-131D

Differential protection: By comparing the difference of the three-phase current, the protection of the generator winding is realized.

Over-current protection: over-current protection to prevent motor overload.

Loss of voltage protection: When the power supply voltage is too low, an alarm or tripping signal is issued.

Undervoltage protection: When the power supply voltage is too high, an alarm or tripping signal is issued.

Zero sequence current protection: Protects zero sequence current to prevent ground faults.

Characteristics of RMC-131D

High sensitivity: It is very sensitive to differential current changes and can detect faults quickly and accurately.

High reliability: The use of advanced digital signal processing technology, with high reliability.

Flexible setting: Flexible setting can be performed according to different protection requirements.

Communication function: Support a variety of communication protocols, convenient remote monitoring and control.

Application of RMC-131D

Power plant: Used to protect synchronous generators.

Industrial enterprises: Used to protect their own generators.

Marine: Used to protect Marine generators.

How RMC-131D works

RMC-131D measures the difference of the three-phase current, and when the difference exceeds the set value, it is considered that an internal fault occurs and a tripping signal is sent.
