AI assessment
- I1.Meets
Does the on-line monitoring module support IEC 61850 Edition 2.1 reporting?
"Online DGA module with DNP3 / IEC 61850 reporting per Sec. 3.4 of the technical proposal."
Vendor declares both DNP3 and IEC 61850 — confirms interoperability with ACME SAS replatforming.
- I2.Partially meets
Tap changer position monitoring — analogue, digital, or fibre?
"MR VRC-1 vacuum on-load (HV)"
Conventional analogue monitoring — adequate but not preferred for the new SAS architecture.
- I3.Not addressed
Cybersecurity — IEC 62443 alignment for the embedded controller firmware?
⚠ This item was not addressed in the vendor's submission. Clarification required before any award decision.
No formal cyber certification declared. Will require explicit IEC 62443 firmware attestation as a clarification.
- I4.Not addressed
Firmware version of monitoring relay and patching commitment?
⚠ This item was not addressed in the vendor's submission. Clarification required before any award decision.
Firmware revision and 5-year patching cadence are not addressed in the submission. Required as a contractual annex.
