Protection in Electric Power Field

We provide services of setting protection on relays in substations, with protections upon investor’s request. Modern testing devices enable us to test and present all the protections placed on the relays. We have experience in setting relay protections on the HET substation in Trebinje, as well as on 13 substations in the territory of Bijeljina.
For mutual communication, relays use the IEC61850 protocol.

For the purpose of better clarity of the system and monitoring, we fit it with a networked relay protection with SCADA system, which enables uninterrupted observation and monitoring in the system. In that, our monitors constantly show changes within the system, as well as any anomalies and failures, as shown in the figure..
