Momentary loss of electric power to mission critical loads can endanger life, cause severe financial losses, or both. Today's 7x24 service centers, data warehouses and critical healthcare facilities demand more than just continuity of power. The quality of power delivered to the load, the effectiveness of periodic system testing and the ability to diagnose outages and disturbances in the electrical system are issues that have serious implications for critical facilities. Poor power quality damages equipment and increases maintenance costs. Inherent power problems stay hidden when testing is ineffective or incomplete. Going beyond source switching and addressing the issues of complete power quality requires a whole new level of ATS capability. The GE Zenith ZTECT closed transition transfer switches go beyond just source switching. Integral metering and communications, high-level diagnostics and superlative flexibility make the ZTECT a perfect solution for today's mission critical source switching. With GE Zenith Controls' high-speed drive system, the overlap of the normal and alternate sources is less than 100 milliseconds. When one source is not within normal limits, such as during a power outage, the ZTECT automatically operates in delayed transition mode.
