GE 8 Series Protective Relay Platform

GE 8 Series Protective Relay Platform

Product Overview: The 8 Series protective relay platform consists of four relays, the 850, 845, 869 and 889, 

which can be used for the protection and management of different power equipment. 

It has two levels of communication capability, with the base CPU supporting multiple protocols and the 

Ethernet port enhanced with the addition of a communication module.

Communication ports: There are four kinds of communication ports: RS485, Wi-Fi, USB and Ethernet; 

RS485 port supports multiple baud rates and protocols, and can be connected to multiple devices; 

Wi-Fi is based on the 802.11 standard, supports WPA2 encryption, and has specific network settings and connecting steps; 

USB port has a fixed IP, and can be connected to the device through the quick connect function; 

Ethernet port has different configuration modes, supports multiple protocols, and can be connected to different power equipment; 

Ethernet port has different configuration modes, and supports multiple protocols, and can be connected to different power equipment. 

Ethernet port has different configuration modes, supports multiple protocols, network settings, routing configuration and status view.

Time Protocol: Supports various time reference sources, such as internal clock, SNTP, IRIGB and PTP IEEE 1588 (version 2), 

you can select the time source for time synchronisation according to the priority level, 

and the PTP protocol has detailed configuration options and status display for accurate time synchronisation.

Communication protocols: Supports various communication protocols such as DNP, IEC 60870 - 5 - 104, IEC 60870 - 5 - 103, IEC 61850,

OPC - UA, etc. Each protocol has specific configuration options and status displays for accurate time synchronisation. 

Each protocol has specific configuration parameters, functional characteristics and application scenarios. 

For example, DNP protocol is used for distributed network communication and supports multiple data types; 

IEC 61850 protocol supports GOOSE and MMS services, which enables fast data exchange and monitoring between devices.

Performance Benefits

Various and flexible communication functions: RS485, Wi-Fi, USB and Ethernet communication ports can meet the communication needs in 

different scenarios; RS485 port supports multiple baud rates and protocols, and can connect multiple devices, 

which is suitable for long-distance and multi-device communication scenarios; Wi-Fi is based on 802.11 standards, easy to configure, 

supports security encryption, and facilitates wireless communication in limited space; 

USB port can quickly establish a connection between the device and the computer through the quick-connect function, 

which is convenient for device configuration; Ethernet port supports multiple advanced protocols after adding the communication module, 

which can adapt to complex network environments. Wi-Fi is based on 802.11 standard, easy to configure, supports secure encryption, 

and facilitates wireless communication in limited space; USB port can quickly establish the connection between the device and 

the computer through the quick-connect function, which is convenient to configure the device; 

Ethernet port, with the addition of the communication module, supports a variety of advanced protocols, 

which is adaptable to complex network environments, and achieves high-speed and reliable data transmission.

Accurate time synchronisation mechanism: Supports a variety of time reference sources, including internal clock, 

SNTP, IRIGB and PTP IEEE 1588 (version 2). According to the actual demand, 

the time source with high priority and high precision can be selected for time synchronisation. 

For example, PTP protocol can provide high-precision time synchronisation, and through the configuration of the relevant parameters, 

it can compensate for the network delay, ensure the time consistency of the various devices in the system, 

and provide accurate timestamps for the event recording and data transmission to ensure the accuracy and reliability of the system operation.

Accuracy and reliability of system operation.

Wide range of protocol support and adaptability: Supports DNP, IEC 60870-5-104, IEC 60870-5-103, IEC 61850, OPC-UA and other communication protocols. 

Each protocol has specific functions and application scenarios. 

For example, DNP protocol is suitable for distributed network communication and supports multiple data types; 

IEC 61850 protocol supports GOOSE and MMS services, which can realise rapid data exchange and monitoring between devices; 

Modbus protocol is widely used, which can realise flexible control of devices and data reading/writing operations through multiple function codes, 

and supports compatibility mode, which can work with different types of devices. 

The Modbus protocol is widely used and can be used for flexible control and data reading/writing operation of devices through various function codes.

High security: In terms of communication security, 8 series protection relay platform can be used as a Radius client to authenticate with 

Radius server through EAP-TTLS protocol, and ensure the authenticity and legitimacy of the identities of both parties in the communication by using 

the certificate management mechanism to prevent illegal access and data leakage. Meanwhile, during data transmission, 

some protocols (such as WPA2 encryption for Wi-Fi) encrypt the data to ensure the security and integrity of the data.
