features:

High functional integration:Integrating multiple functions into one device,including protection,control,measurement,communication,and monitoring,reduces the number and complexity of equipment,and improves the reliability and stability of the system.

Fully functional protection:Provides directional or non directional overcurrent and ground fault protection,as well as overvoltage,low voltage,zero sequence voltage protection,thermal overload protection,sensitive grounding protection,and quick break grounding protection(including intermittent grounding protection).

Strong communication capability:Supports IEC61850 protocol,truly realizing mutual communication between intelligent devices in the station.It also supports industrial standard Modbus communication protocol and IEC60870-5-103 communication protocol,with high communication efficiency and powerful functions.

User friendliness:A large LCD display with editable single line diagrams,which can be accessed through an easy-to-use human-machine interface(HMI)locally or based on a web browser,making it convenient for users to operate and monitor.

Strong scalability:It can be configured and expanded according to actual needs to meet different protection requirements.

effect:

Mainly used for monitoring and protecting feeder lines in power systems.When a fault occurs in the feeder line,it can quickly and accurately determine the type and location of the fault,and take corresponding protective measures,such as cutting off the faulty line,preventing the fault from expanding,and ensuring the safe and stable operation of the power system.At the same time,it can also measure and monitor the operating parameters of the power system,providing data support for the scheduling and management of the power system.

Purpose:

Widely used in the power industry such as substations and power plants.

Suitable for industrial users such as cement,metallurgy,petrochemicals,automobiles,semiconductors,papermaking,tobacco,etc.

It can also be used in industries such as municipal,airport,port,and real estate.
