DZ9 Teleprotection Equipment
The DZ9 device enables the transmission of up to 8 independent protection commands over different digital communication channels and up to 4 independent protection commands over analog communication channel. Channel coding and adaptive command detection algorithms are ensuring the optimal combinations of the transmission time, security and dependability in the current transmission conditions.
The DZ9 supports Ethernet connection to protective equipment in accordance with the IEC 61850 standard. GOOSE command interface can handle up to 8 commands. Relay type and GOOSE type command interfaces can operate in parallel in the same DZ9 device. GOOSE messages from one substation can be released via relay type command outputs in a remote substation.
Complete configurability and modularity of the DZ9 device offers users to adapt the device easily and in user-friendly way to the control systems requirements and to the characteristics of the transmission media.
