Industry: Energy and Utilities Organization: EW Sennwald Location: Sennwald, Switzerland Year: 2024
At a Glance
Plants connected
Two hydropower plants and five photovoltaic systems
Diagnostic values
Five key signals monitored live
Detection
A developing fault was identified before failure
Operator experience
Daily operation does not require the specialist interface
Overview
EW Sennwald wanted to manage and monitor its energy production centrally. Specialist SRT Diagnostics software provides valuable predictive-maintenance information, but its complexity made it unsuitable for everyday operation and had contributed to incorrect handling.
Implementation
Together with the diagnostic-system manufacturer, the five most important values were selected and integrated into BuildingPro Suites. Operators can review them in dashboards and monitor them with rules and alarms. Other plant sensors are integrated as well; for example, flow measurements can be reported automatically to the environmental authority.
The operations center also provides plant control without requiring users to enter the specialist diagnostic system.
Proactive Maintenance Result
A technician observed a small increase in acceleration together with a general temperature decrease. This combination prompted an early inspection, helping avoid a possible malfunction or failure.
The project shows how a building and infrastructure platform can translate a small number of specialist diagnostic indicators into accessible dashboards and actionable rules. This supports proactive service while reducing the risk of incorrect interaction with complex expert software.
