Differential current relays have the following features:

Accurate and reliable: differential relays are mainly used for protection control in power systems, and PCM4.3 has the characteristics of accuracy and reliability. The differential relay determines whether there is a fault according to the difference of current flow in the system, so its measurement and judgment of current is very accurate, and it can detect system faults in time and carry out protection and control, effectively ensuring the safe and stable operation of the power system.

Sensitive operation: The differential relay has the characteristics of sensitive operation in the working process. When a fault occurs in the system, the response speed of the differential relay is very fast, which can reflect the location and scope of the fault, and cut off the fault circuit in time to avoid the expansion and impact of the fault, and ensure the stable operation of the power system.

Fast response speed: The response speed of the differential relay is very fast, and it can immediately respond and cut off the fault circuit when the fault occurs, so as to avoid the expansion and impact of the fault. This feature is due to the fact that the differential relay uses high-precision electronic components as the basis for measurement and judgment, and its working mechanism is to determine whether there is a fault in the system by instantaneous comparison of the current size in different circuits.

Strong scalability: The scalability of the differential relay is very strong, and PCM4.3 can cope with the needs and requirements of different systems. Differential relays can be customized according to the characteristics of different systems, providing a variety of solutions to meet the protection needs of different systems. In the choice of protection scheme, differential relay provides a variety of options, can flexibly respond to a variety of different system needs, to achieve the best protection control effect.
