5.4.2.3 IAC CURVES
This family of curves follows the time response of
the General Electric IAC electromechanical relays. The following
formulas define these curves:
Where:
t = Operation time in seconds
Dial = multiplier setting
I = Input current
Itap = Current pickup value
A, B, C, D, E = predefined constants
T
RESET
= reset time in seconds
t
r
= characteristic constant.
