Tidaholms Elnät improves voltage monitoring and customer dialogue with Aidon One

As more electric devices and local energy sources put pressure on the grid, monitoring of voltage quality is important to keep the power supply stable and reliable. Aidon One enables daily monitoring of distribution voltage quality in accordance with the EN 60150 standard, based on the 10-minute measurement data from Aidon meters.

One of the first DSO’s to test and start using voltage quality monitoring in their network was Tidaholms Elnät. According to Head of Electricity and Local Distribution Network Magnus Sjögren, the rise of electric vehicles has increased customer expectations. As larger loads become more common and the grid becomes more dynamic, maintaining voltage levels is becoming more demanding.

– We want to investigate proactively how things change over time, rather than simply reacting to customer calls, Sjögren says.

Day-to-day monitoring with Aidon One

In Tidaholm, the operations team uses Aidon One as a daily tool. Through the user interface, the team views continuously updated alarms, which help them quickly see what requires attention. Historical voltage data supports long-term analysis and helps identify gradual changes.

– In the short time we’ve been using it, Aidon One has helped us become more proactive in our thinking and in how we work, Sjögren says.

Turning alarms into insight

Voltage alarms are not always straight forward. Tidaholm has found that undervoltage alarms may sometimes be linked to the electricity supply, but often point to other issues, such as faults on the customer side.

By reviewing alarms alongside statistics and historical data, the operations team becomes faster at recognising patterns and identifying likely causes. As Customer Service Manager Per Jakobsson explains:

– If you’re curious enough, you can learn a lot from the alarms. You start to see the bigger picture and how things are connected.

Data-driven customer service

Aidon One has also improved how Tidaholm investigates and responds to customer concerns. In one case, the team sent the in-built Aidon PDF report when a customer suspected EV charging was causing an issue. The data showed a different root cause, helping the team steer the investigation in the right direction and avoid unnecessary troubleshooting.

In another case, a customer believed they were experiencing overvoltage. Aidon One confirmed that this was not the case, enabling the team to clarify next steps with confidence.

– You can quickly check the levels in Aidon One, see if there are any issues, and then dig deeper if needed. It makes customer conversations faster and more professional, which is a nice bonus, Magnus Sjögren says.

A more proactive way of working

The Tidaholm team sees monitoring as an area of growing importance. With Aidon One, they are moving from reactive troubleshooting to a more proactive approach, supported by better visibility and data.
