Time Adder:
An adder is an increment of time that is added to the time
for each current for a particular curve. An adder by itself flattens the high
current portion of the TCC Curve.
Minimum Response Time Adder (MRTA):
Establish a minimum control
response time independent of the selected TCC
The Graph button shows the graphic of the user selected time characteristic, as
shown in Figure 3-28. In this example the graphic corresponds to a Standard Inverse
ANSI Curve with time dial of 0.50.
Figure 3-28 Time characteristic graphic
The integration of the instantaneous and the time curves can be performed clicking
the
Final Characteristic button
, as shown in Figure 3-29
