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


The VCL-TP Teleprotection - IEC-61850 GOOSE over IP/MPLS equipment is a compact, 1U high, 19-inch rack mountable equipment that is designed transport IEC-61850 GOOSE* messages over a routable IP/MPLS network. (*Generic Object Oriented Substation Event.)

VCL-TP is designed to transmit / receive the IEC-61850 compliant “Digital Substations” to provide “Distance Protection” over IP / MPLS links using IEC-61850 GOOSE messages instead of “Binary” commands.

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.

VCL-TP Teleprotection - IEC-61850 GOOSE over IP/MPLS is extremely fast and reliable “Distance Protection” device that offers up to 4, 2-way independent command channels which can be operated selectively, or collectively over an IP / MPLS / Ethernet network with an extremely high degree of reliability and security. Additional features such as “Firewall” have been incorporated to guard against any possibility of “cyber-attacks”, making the equipment a best-in-class device.
