Custom Testing Interface for Circuit Breakers, FHNW School of Computer Science

Developing a new circuit breaker requires extensive testing to ensure safety, reliability and compliance with industry standards. Engineers need to run large numbers of test sequences while continuously monitoring and analysing the resulting measurement data.

At Pfiffner, the existing Cibano 500 software limited the number of test sequences that could be executed consecutively. This made long-running and automated test scenarios less efficient and required additional manual effort.

The student team developed a custom web-based application that communicates directly with the Cibano 500 API. It enables engineers to configure and execute an unlimited number of test sequences while automatically collecting and storing the resulting measurement data.

Existing Omicron test files can be imported, edited and reused, allowing the solution to fit into established workflows. A familiar and intuitive interface makes it easy to organise tests into groups, adjust technical parameters and monitor their execution.

After each test, measurement data is automatically collected and visualised. Engineers receive live updates throughout the testing process and can analyse results directly within the application.

By combining test configuration, automated execution, monitoring and data visualisation in one interface, the solution reduces manual effort and makes complex testing processes more efficient.

The project demonstrates how custom software can overcome limitations of existing industrial tools while integrating with established hardware and workflows.

Expertise in software engineering, API integration, process automation and data visualisation can be applied to many industrial challenges; from automating repetitive processes to connecting specialised equipment and making measurement data easier to analyse.
