Output Format of Harmonic Analysis Data
Data Format
Harmonic analysis data normally consists of a 8-byte header and 11 bytes of data
Header Data
Header Section
The header section consists of 8 bytes (h1 to h8).
h1 h2 h3 h4 h5 h6
h8h7
h1 to h3 : data type
V__ : voltage A__ : Current W__ : Active power
DEG : Phase angle between the 1st order voltage and 1st order current
DGV : Phase angle between the 1st order voltage and the 2nd to 50st order voltage
DGA : Phase angle between the 1st order current and the 2nd to 50st order current
PF_ : Fundamental power factor (1st order)
HzV : Fundamental frequency of the voltage of the PLL source
HzA : Fundamental frequency of the current of the PLL source
THD : Harmonic distortion (either IEC or CSA)
CNT : Relative harmonic content
MEM : Data number in case of recalling
h4: Element
1: Element 1 2: Element 2 3: Element 3 4: Not applicable
h5: Data state
N: normal I: Overrange O: Computation overflow P: Peak overflow
E: No data
h6, h7: Order
01 to 50: Order of fundamental or higher harmonic (up to the maximum analysis order).
“__” (space) will be assigned in case of frequency, harmonic distortion, power factor or in
case of all computed values of the 1st to 50th order.
h8: Indicates data lag/lead in case of DEG data type. In case of other data types, __ (space)
will occur.
G: Lag D: Lead _: Not detectable
Data Section
The data section consists of 11 bytes.
d1 d2 d3 d4 d5 d6 d7 d8 d9 d10 d11
d1 : polarity; __ (space) or – (minus)
d2 to d8 : mantissa, floating-point number of the maximum six digits
In case of harmonic distortion and relative harmonic content :
d9 : %
d10 to d11 : __ (space)
In other cases :
d9 to d11 : exponent; E-3 → m, E+0, E+3 → k, E+6 → M
