VCL-TP, Teleprotection IEC 61850 GOOSE over IP / MPLS Interface

Description

VCL-TP Teleprotection - IEC-61850 GOOSE over IP/MPLS equipment is a 2U high, 19-inch rack mountable equipment that is designed transport IEC-61850 GOOSE* (*Generic Object Oriented Substation Event) messages over an IP/MPLS network. The equipment also provides 8 Binary Inputs / Outputs and performs GOOSE to Binary / Binary to GOOSE functions, thereby allowing the users to install VCL-TP Teleprotection - IEC-61850 GOOSE over IP/MPLS equipment between sub-stations where one sub-station (protection relay) is using GOOSE messages and the other complementing sub-station (protection relay) is using binary commands.

The VCL-TP Teleprotection - IEC-61850 GOOSE over IP/MPLS incorporates the same level of “reliability” and “dependability” that the users have come to expect of the IEEE C37.94 based communication interface. Additionally, the VCL-TP Teleprotection - IEC-61850 GOOSE over IP/MPLS provides un-paralleled security, speed as well as all the advantages of an IEC-61850 GOOSE based system operating in a “Digital Sub-station” environment.

The VCL-TP Teleprotection - IEC-61850 GOOSE over IP/MPLS is extremely fast and reliable “Distance Protection” device that offers up to 8, 2-way independent command channels, each of which can be operated independently over an IP / MPLS / Ethernet network with an extremely high degree of reliability and security.
