table voltage & Current section (tdd, thd eVEN, thd ODD, OVER-DEVIATION,
UNDER DEVIATION) calculation method:
Total Demand Distortion – TDD – is the current distortion (harmonics above the 1st)
as a percent of maximum demand load. TDD is defined using the following
relationship:
C = Harmonic RMS Value
n = Harmonic Order
C = Harmonic RMS Value
n = Harmonic Order
The Over-Deviation indicates how much higher the RMS Voltage is than the
Reference Voltage
The Under-Deviation indicates how much lower the RMS Voltage is than the
Reference Voltage
