WHAT IS THOMS?

The THomassen On-lineMonitoring System (THOMS) is an intelligent condition monitoring system that securely gathers data from gas turbine systems anywhere in the world. The data is used for real-time display, trending
and analysis. This system can help to reduce costs
significantly.

HOW DOES THOMS WORK?

The local THOMS data acquisition station connects directly to the Speedtronic MARK V arcnet network or the Speedtronic MarK VI and the ATH TC7 ethernet network.
This provides access to all turbine data, including measurements, setpoints, status information and alarm indications. The gas turbine owner physically enables data transfer to the remote THOMS station at ATH headquarters
in The Netherlands, where the data is analyzed.

WHAT DOES THOMS DO?

Real time monitoring
THOMS enables quick analysis of malfunctions in gas turbine installations, helping minimise downtime. Experts at ATH headquarters can guide on-site operators and maintenance personnel through the control system logics and view the overall status of gas turbines, control system hardware, and software. This feature is very useful for troubleshooting

Historical data trending
Long-term trending and analysis of vital local operating machine data helps:
• prevent possible damage to systems
• personnel make more efficient maintenance decisions
• enable exact calculations of inspection intervals.

Measuring compressor and unit efficiency
THOMS enables ATH experts to provide an accurate understanding of the condition of a client’s gas turbine by calculating overall and component efficiencies and regularly presenting data to the client.

WHO CAN BENEFIT?

THOMS benefits all users of gas and steam turbines equipped with Speedtronic Mark V, Mark VI or ATH TC7 control systems.
