PRODUCT SETUP
Pt = 0.017 * P
For a max power 100000 KW * 2.4 = 240000 KW, we transmit
Pt = 0.017 * 240000 = 4080
A value above 240 MW is indicated by overflow.
Example 2: Nominal voltage Vn = 500000 V
Since RMS voltage V can be only positive:
Transmitted voltage Vt = (8191/(Vn*2.4)) * V - 4096 =
= (8191/(500000 * 2.4) ) * V - 4096 = 0.0068 * V - 4096
a = 0.0068
Since the step is in increments of 0.001, we round it at:
a = 0.006
b = -4096
Vt = 0.006 * V - 4096
For max voltage 500000 V * 2.4 = 1200000 V, we transmit
Vt = 0.006 * 1200000 - 4096 = 7200 - 4096 = 3104
