Digital Energy  Power Quality  Automatic Transfer Switches


Momentary loss of electric power to mission critical loads can endanger life, cause severe financial losses, or both. Todays 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.

 

ZTE – Standard (Open) Transition
The GE Zenith ZTE standard (open) transition transfer switches  
go beyond just source switching. Integral metering and communications, high-level diagnostics and superlative flexibility make the ZTE a perfect solution for today’s mission critical source switching.  
ZTED – Delayed Transition
The ZTED - Delayed Transition transfer switch offers the same features as the ZTE with the addition of an adjustable time delay in the centered "off" position. This delay allows motor loads to coast down and transformer field to decay; ensuring inductive loads are re-energized after transfer with only normal inrush starting currents.
ZTECT – Closed Transition
The ZTED - Delayed Transition transfer switch offers the same features as the ZTE with the addition of GE Zenith Controls' high-speed drive system, which ensures 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.
