Argentina (CAMMESA PT-4) ride-through requirements
Frequency ride-through for Argentina. Every breakpoint below is read from the code itself, and carries the clause it came from — so you can check it, not just cite it.
What is the frequency ride-through envelope for Argentina (CAMMESA PT-4)?
The plant must ride through between the upper and lower bands. The upper (over-frequency) band holds 52.5 Hz from t = 0 to 15 s; then 52 Hz from 15 s to 25 s; then 51.5 Hz from 25 s to 100 s; then 51 Hz from 100 s onward — the last band the envelope defines, with no stated end time. The lower (under-frequency) band holds 47.5 Hz from t = 0 to 15 s; then 48 Hz from 15 s to 25 s; then 48.5 Hz from 25 s to 100 s; then 49 Hz from 100 s onward — the last band the envelope defines, with no stated end time.
Every breakpoint is stated in the clause cited below.
Applies to ERNC parks / generators joining the MEM-SADI grid

The clause this came from
CAMMESA, LOS PROCEDIMIENTOS – P.T.4, numeral 2.2.3.2 lit. b) 'Rangos de frecuencia admisibles de operación' (Pág. 6) + 'Curva límite frecuencia-tiempo / Zona Admisible' (Pág. 7); applied to ERNC parks by ANEXO I numeral 9.8.5. Versión 03-Oct-2023.
Who does Argentina (CAMMESA PT-4) bind, and since when?
ERNC parks / generators joining the MEM-SADI grid. 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). That is a gap on this site, not a statement that Argentina (CAMMESA PT-4) 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)
- Does Argentina (CAMMESA PT-4) 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) 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) itself?
- Yes. Every breakpoint is read from the code, and each envelope carries the clause it came from, quoted in full under its chart — so you can check the figure against the standard rather than cite it from this page.
- Which events are charted for Argentina (CAMMESA PT-4)?
- Argentina (CAMMESA PT-4) is charted here with 1 envelope — frequency ride-through (FRT). No low-voltage or high-voltage envelope is charted here — check Argentina (CAMMESA PT-4) 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.
