Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1) ride-through requirements
Low-voltage ride-through, High-voltage ride-through for Argentina. Every breakpoint below is read from the code itself, and where a point was taken off a published figure rather than stated in the clause, the section under that chart says so — a curve with no recorded source class.
What is the low-voltage ride-through envelope for Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1)?
The plant must ride through for any voltage that stays on or above this envelope. The envelope holds 0 pu from t = 0 to 120 ms; then 0.5 pu from 120 ms to 900 ms; then 0.7 pu from 900 ms to 1 s; then 0.9 pu from 1 s to 20 min; then 0.95 pu from 20 min onward — the last band the envelope defines, with no stated end time.
Check these points against the clause quoted below before relying on them.
| From | To | Voltage | Between the points |
|---|---|---|---|
| 0 | 120 ms | 0 pu | Held flat |
| 120 ms | 900 ms | 0.5 pu | Held flat |
| 900 ms | 1 s | 0.7 pu | Held flat |
| 1 s | 20 min | 0.9 pu | Held flat |
| 20 min | no stated end | 0.95 pu | Held flat |

What is the high-voltage ride-through envelope for Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1)?
The plant must ride through for any voltage that stays on or below this envelope. The envelope holds 1.2 pu from t = 0 to 120 ms; then 1.1 pu from 120 ms to 20 min; then 1.05 pu from 20 min onward — the last band the envelope defines, with no stated end time.
Check these points against the clause quoted below before relying on them.
| From | To | Voltage | Between the points |
|---|---|---|---|
| 0 | 120 ms | 1.2 pu | Held flat |
| 120 ms | 20 min | 1.1 pu | Held flat |
| 20 min | no stated end | 1.05 pu | Held flat |

Who does Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1) bind, and since when?
This code does not carry a short scope statement — read the clause quoted above for who it binds. No date of effect is published here — grid codes are reissued, so check the current issue before relying on it.
These figures are a reading aid, not legal advice. Grid codes are reissued: verify against the current edition before you design to them.
Digitised operating parameters beyond ride-through — droop, reactive capability, operating ranges — are published for 36 of the 66 codes in this atlas, not yet for Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1). That is a gap on this site, not a statement that Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1) sets none — the atlas hub marks the codes that carry them.
Curve data last checked against the code on — 66 standards, 130 envelopes, published by bess.engineer under CC BY 4.0.
Questions this page answers about Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1)
- Does Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1) require ride-through, or only that the plant does not trip?
- Ride-through. Every envelope on this page is a performance duty the plant must meet, not a protection-setting no-trip boundary — they are different obligations. That is what these curves are; they are not everything Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1) contains. The requirement sentence under each chart says which side of the curve is the compliant one.
- Are the numbers on this page taken from Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1) itself?
- Every breakpoint is read from the code, and where a point was taken off a published figure rather than stated in the clause, the section under that chart says so — on this page that includes a curve with no recorded source class. The clause each curve came from is quoted under it.
- Which events are charted for Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1)?
- Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1) is charted here with 2 envelopes — low-voltage ride-through, high-voltage ride-through (LVRT, HVRT). No frequency envelope is charted here — check Argentina (CAMMESA PT-4 Anexo I, Fig. Ai.1) itself before concluding it sets none.
Ride-through, in context.
An envelope is a compliance boundary; understanding why it exists is a different question. The ride-through and grid-forming entries cover the engineering, and the Engineering Foundations course builds it from the physics up.
