Product Description
The GARD 8000® Teleprotection channel is a revolutionary product platform that provides the user with a fully programmable system that can be used for Direct Transfer Trip, Permissive Transfer Trip, Blocking, and Unblocking applications. The product is unique in that the same platform is used for analogue, digital, and IEC 61850 LAN tripping applications. The base system is the digital platform that can be used to transmit and receive up to 32 functions in groups of 8. Each block of 8 commands is transmitted over a 56/64kbs data channel, these data channels can be any of the supported digital interfaces. In essence the user is provided a teleprotection channel that has four conventional 8-function teleprotection systems built-in for the price of one.
Based on the RFL® 9745 Teleprotection channel, the GARD 8000 Teleprotection system carries relaying communications to the next level. The system uses fully programmable logic and settings that can be uploaded or downloaded using the built-in TCPIP (electrical or optical) or RS-232 interface. Communicating with the system is done with either a laptop PC using Web Browser, or, with the optional built-in color TSD (touch screen device) that communicates with the GARD. The GARD 8000® has a built-in web server that contains all of the user settings. No special or proprietary software is required to access the product. A most unique feature is that the user manual and customer system and application drawings are stored.
The GARD 8000® is available in a 3U chassis (5.25") which can support up to two additional analog or digital teleprotection function modules, or a 6U chassis (10.50") which can support up to eight analog or digital teleprotection function modules. Other GARD 8000® communications or protection modules can be used in the chassis if desired. Redundant controller and power supplies are available as options for applications where ultra reliable systems are required.
