Iterative UX design improvements on their Windows Software for Partial discharge analysis on instrument transformers

Omicron serves the electrical power industry with innovative products and services for testing, diagnostics and monitoring of assets worldwide.

Partial discharges (PD), as defined by IEC60270, are localized dielectric discharges in a partial area of a solid or liquid electrical dielectric insulation system under high voltage field stress (high voltage). Partial discharges in a transformer deteriorate its insulation and can lead to failure of the transformer.


Solving interaction problems in a one day workshop often takes more time than some stakeholder actually have. Together with the developers and users we look out for problems in the interaction. Splitting complex interactions into several microinteractions helps to improve the overall user experience step by step.

We then generate click-prototypes from the all new constructed microinteractions. These prototypes mostly are quick and dirty and should only work for testing different interaction motivations between the user and the software.

These prototype feedback rounds are incredible useful for us and often spark new questions to think about. Usually there are more than three iterations needed to get to a satisfying result.

The intelligent design of the interface and the interactions combined, builds the overall user experience

To make sure everyone is on the same page it is important to know the requirements. They can coming from developers, product owners, the users and many other stakeholders. This needs to be communicated before any further steps are being made.

In addition to that, use cases can help identify hidden needs and problems of certain users. Ignoring the different motivation in the process of the development can lead to a product which will not be liked to work with. (You know.. like the Office Suite in the 90’s)

This image shows a redesign after many users complained about the design and the complexity of this actual easy task.

The user can choose what data from what channel and device should be recorded. We decided to make a file browser like pop up window for the reduction of distractions.

Feedback Feedback Feedback

Designing without feedback is like walking blindfolded. You don’t know what and when it hits you. Although this metaphor is bad and I should feel bad, it shows my point. It’s incredibly important to gather as much feedback as possible from every stakeholder involved in this project. We can get feedback, questions to think about and a general communication may spark new ideas on both sides.
