A 110/20 kV substation with six feeders on IEC 60870-5-104: transformer thermal margin, tap changer wear, and a full recloser sequence.

How it works

A distribution substation: 110/20 kV with six feeders, 9 devices and 69 points over IEC 60870-5-104.

Protection events are why this solution exists. The interesting data arrives in bursts rather than as a steady poll, and the demonstration is what an Edge does with a burst: capture it at the resolution it happened, not at the rate someone chose to sample.

The money moments are transformer thermal margin treated as a forecast rather than a threshold, a tap changer wear counter that accumulates towards maintenance rather than alarming after it, and a complete recloser sequence captured end to end on the wire.
