Icelandic grid operator Veitur supplies the capital of Reykjavik and the southwest of the island – and therefore around 56 percent of the country's population – with electricity. As Technical Manager, Rúnar Svavar Svavarsson is responsible for keeping the 23 transformers of the power grid in operation. For monitoring, the service technicians have had to stand by in primary substations to read off the important condition indicators, such as gases in the oil or the winding temperature. Since this is very time-consuming, Svavarsson wants to gradually digitize the transformer fleet with ETOS®.
