KONCAR - Model EMBB -Electrical Machine Black Box
The EMBB monitoring system records all harmful working conditions that are not allowed or represent a potential danger to the machine’s lifetime. By equipping the synchronous and asynchronous machines with EMBB system owners and users get an additional insight into the harmful working conditions during machine operation. EMBB allows a better asset management, and a reliable monitoring of the machine, especially during the warranty period.
