In modern digital substations, the IED’s are connected through an IT network where the communication is digital and follows the IEC 61850 standard, an international standard where Megger has been contributing to its evolution since Edition 1. The primary data is also digitised through merging units and published as Sampled Values at a network called process bus.
These IEC 61850 networks require specialised solutions to effectively verify that the substation is properly configurated and Megger has been providing such since 2009. For example, to capture the current data traffic and compare that with the specified and authorised data traffic helps to identify potential problems and in worst case, unauthorised data traffic by intruders.
Once you select your preferred single or multi-function relay protection tester, make sure you include the GOOSE and Sampled Values pin in your package. To do this, please write the correct number in the internal software option.
