Seven relays, one RTAC, no assumptions
A public utility district needed seven substation feeder relays brought into SCADA through a new real-time automation controller. Our team programmed the RTAC and delivered the complete integration package.
BUILT FROM THE AS-BUILTS
The RTAC was programmed directly from the relays’ as-built settings and logic. Control schemes, interlocks, and per-relay differences were verified from source files, not assumed.
DNP3 POINT ENGINEERING
The point map to the Survalent master uses generic relay names, so future relay changes only touch the master station file. Ready-to-load point files and a commissioning test sheet shipped with the work.
The controls work the way the protection engineer intended, because they were built from what the protection engineer wrote.
BOTTOM LINE
- A client needed seven relays speaking to SCADA, correctly.
- Our team delivered the RTAC, the point maps, and the proof.
