37.21 ULC underload
point 1
Defines the first of the five points on the Y-axis that together
with the corresponding point on the X-axis (37.11 ULC speed
table point 1…37.15 ULC speed table point 5 or 37.15 ULC
speed table point 5…37.20 ULC frequency table point 5)
define the underload (lower) curve.
The following conditions must be fulfilled:
• 37.21 ULC underload point 1 <= 37.31 ULC overload point 1

• 37.23 ULC underload point 3 <= 37.33 ULC overload point 3
• 37.24 ULC underload point 4 <= 37.34 ULC overload point 4
• 37.25 ULC underload point 5 <= 37.35 ULC overload point 5
10.0%
-1600.0…1600.0% Underload point. 1 = 1%
37.22 ULC underload
point 2
Defines the second underload point.
See parameter 37.21 ULC underload point 1.
