The Toshiba GRZ100 distance protection meets the functional and performance requirements of the IEC 61850 standard implemented in a software environment and hardware architecture that will support future technological progress.
The relay certified by KEMA in July 2006 demonstrated the high performance achieved for GOOSE messaging and is the first of several Toshiba IEC 61850 products with transformer and line differential relays coming soon.
Interoperability has been demonstrated at a number of events including several organised by the UCA International Users Group supported by multi-vendors in a virtual substation environment.
The advanced numeric design of the relay features command protection schemes using integral digital communication channels and programmable logic to reduce system costs and complexity. Other advanced techniques are included to enable, for example, tripping for faults that occur during power swing conditions.
