DZ8 Analog Teleprotection Terminal - - Thiết bị tự động hóa công nghiệp - ANS Vietnam

Teleprotection equipment is one of the most important components in power systems protection, enabling fast and selective isolation of defective HV lines. The DZ8 teleprotection equipment is a basic building block of command type teleprotection system.

Main features

• Duplex transmission of up to four protective commands over analog transmission channels
• Programmable command transmission characteristics permit adaptation to any protection scheme
• Optimum Digital Signal Processing algorithms for secure and reliable operation via PLC channels with the highest possible transmission rate
• Signal boosting for full exploitation of the available transmission power for each protective command
• Redundant command input and output, preventing false operation due to single component failure
• Equipment setting and monitoring through built in MMI console or personal computer
• Loop Test - automatic or manual
• Internal real time clock (RTC) with provision for external clock synchronization
