EC670/650 intelligent microcomputer protection device can be used as a variety of substation wiring methods

Control, monitoring and protection devices for circuit breakers, isolating switches and ground switches.

These two devices, both based on IEC 61850 standards, have a wide range of applications

Sex. The design of the REC670/650 reflects the core values of the 61850 standard, thus ensuring that

Maintain an open, flexible and future-proof system architecture with the most current

Advanced performance. Therefore, the REC670/650 series device is the old station upgrade and new

Ideal for building substation applications.

The REC670’s outstanding on-off capacity enables multiple intervals to be achieved with a single device

Control. For example, a single REC670 device has the ability to connect a string of 1 1/2 wiring modes at intervals

All equipment in the test and control function, and including all circuit breaker failure protection. Due to the

Therefore, the REC670 can be used at any voltage level that includes different protection and control systems

For any substation, simplify system design and effectively reduce costs.
