A tester for the new digital grid
Zeus is a tester designed to install and maintain the communications in the power industry. It supports legacy and new generation interfaces in order to verify Ethernet / IP, PTP, SyncE, ToD, IRIG-B, T1 / E1, C37.94, RS-232, G703 and protocols such as GOOSE, SV or MMS, therefore you will get a perfect vision and control of your infrastructures improving protection and data acquisition.
In substation automation many resources require accurate synchronization ranging from microseconds to milliseconds:
- Applications that use SV / GOOSE /PRP eed to minimize latency.
- Data acquisition at IED, RTU and MU.
- SCADA and the MMS protocol.
- Line protection schemes.
- Events recording.
- Synchro-phasors deployed across the WAN to monitor the power grid.
Zeus has a complete set of features for time commissioning by means of measurements, analysis and protocol emulations of PTP, IRIG-B, GPS, SyncE, T1/E1, 1PPS
