Sequence of Operation (cont’d)

Bypass-Isolation Operation

An automatic transfer switch equipped with a bypass-isola- tion switch provides the ability to withdraw the ATS for test- ing and/or maintenance purposes without interrupting the served load.

Operation of the unit is quick and convenient requiring only one operator and less than one minute to complete. Instructions are mounted on the front of each isolation switch door along with a mimic panel providing indication of power source availability and ATS/bypass switch positions.

The bypass switch is normally open on both sources with the ATS feeding the system load. During operation, the bypass is closed paralleling the ATS contacts which then allows withdrawal of the ATS to the “TEST” or “ISOLATE” positions. Mechanical and electrical interlocks are included to prevent cross-servicing or bypassing to a dead source.

In the “TEST” position, the ATS is disconnected from the load (now fed through the bypass) but control power is present to allow complete operational testing through the control panel of the transfer switch

In the “ISOLATE” position, the ATS is completely withdrawn and may be removed from the enclosure for maintenance if desired.

After the isolation operation, if the bypass is closed

on Source 1 and if this source fails, an auxiliary contact on the bypass control will automatically start the engine-generator set. When the second source is available, the manual handle of the bypass may be operated to transfer the load to the available source. Interlocks prevent both this transfer, if the ATS is in the circuit and connected to the opposite source or reconnection of the ATS unless the positions match.

WARNING

While the bypass switch is out of the AUTO position/mode, the ATS is INHIBITED from automatic operation. Make certain the ATS is left in automatic after completion of any service.

ZBTS, ZBTSD specifications

General Electric (GE) has established itself as a leader in the field of industrial automation and control systems, with its ZBTSD and ZBTS series representing some of the most advanced technology available. These systems are engineered to enhance performance, efficiency, and reliability in various industrial applications.

The ZBTSD, or Zero-Based Time Series Data, is designed to optimize data storage and retrieval processes. One of its main features is its ability to provide real-time monitoring and analytics of dynamic processes. This capability is crucial for industries that require immediate insights into their operations, helping to minimize downtime and enhance decision-making. The ZBTSD utilizes advanced machine learning algorithms to identify trends and patterns, enabling predictive maintenance that can significantly reduce operational costs.

On the other hand, the ZBTS, or Zero-Based Time Series Solutions, focuses on delivering comprehensive solutions for time series data management. This system is adept at handling vast amounts of data generated by industrial equipment, ensuring that organizations can efficiently process and analyze this information. Key characteristics of ZBTS include scalability, which allows companies to expand their systems as their data grows, and flexibility, permitting integration with various data sources.

One notable technology employed in both ZBTSD and ZBTS is cloud computing. By leveraging the cloud, these systems offer enhanced data accessibility and collaboration capabilities. Users can access critical data anytime, anywhere, facilitating timely responses to operational challenges.

Another significant feature is robust cybersecurity measures. With the increasing number of cyber threats in industrial environments, GE has prioritized security in the ZBTSD and ZBTS systems. These solutions are equipped with advanced encryption protocols and user authentication mechanisms to protect sensitive data from unauthorized access.

The user interface of both systems is designed to be intuitive, allowing operators to interact with the systems efficiently. Customizable dashboards provide visual representations of key performance indicators, making it easier for users to comprehend complex data at a glance.

In summary, GE's ZBTSD and ZBTS systems exemplify the integration of cutting-edge technology in industrial automation. Their emphasis on real-time data analytics, scalability, cybersecurity, and user-friendly design positions them as invaluable tools for organizations seeking to enhance operational efficiency and decision-making. As industries continue to evolve, these systems will play a pivotal role in shaping the future of industrial automation and data management.
