C37.94 is a widely used method in the industry for protecting power lines. It automatically trips a breaker on a line in the event of a fault, to isolate the fault and minimize damage to equipment and interruptions to power supply.

xGenius and Zeus can simulate TDM network dynamics by generating impairments on a line that controls the C37.94 protection protocol. It is essential to test the impact these errors may cause in the lab or the field.

Protection schemes, such as C37.94, have the objective of keeping the Power System stable and isolated. For correct function the control of latency, latency variations and asymmetry is fundamental.

Zeus helps to design, install and maintain all the communication networks of the Power Utilities including the new ones based on IEC 61850 standards sucha as PTP or GOOSE, and legacy protocols as such as IRIG-B or C37.94.

xGenius is a tester to install and maintain Telecom and Utility networks with new and legacy interfaces including GbE up to 10G, PTP, NTP, SyncE, ToD, IRIG-B, T1 / E1, C37.94, RS-232, G703, and it also captures protocols like GOOSE, SV or MMS.

Teleprotection systems must isolate faults very quickly to preventing damage to the network and power outages. The IEEE committee defined the C37.94 as a optical fibre interface to providecommunications between relays and multiplexers.
