For each signal, every second, TRIDENT H acquires and stores 256 samples at 6400Hz. 
When measuring line voltages, TRIDENT H samples over the same period the two phase 
voltages, and then instantly calculates the difference so as to obtain a « sample » of the line 
voltage. 

 

B)

 

Calculation of the « instantaneous » harmonics 

 

When the acquisition of the 256 samples of the voltage and current of a phase is finished, the 
harmonic calculation algorithm is applied to the 2 tables of 256 samples. 
In this way the amplitudes of the first 41 harmonics of the 2 signals are obtained, from which 
are calculated the THDs and TDDs of the phase in question. 

 

C)

 

Calculation of “mean” values 

 

At the end of the integration period, the mean values of the amplitudes of the first 25 harmonics 
and the mean THDs and TDDs are calculated. 
All these mean values are compared with the thresholds configured in TRIDENT H, and if there 
are out-of-limits the counters are updated. 

 

D)

 

Memory updates 

 
When the mean values are available, the THDs and TDDs are stored in the corresponding 
memory, as well as the values of the 6 signals, for each of the 3 chosen harmonics, in the 
harmonic memories.

Measurement inputs and accuracies

 

See TRIDENT 3U3I manual.

 

The accuracies are given at 23°C.   All AC measurements are True RMS.  
In the following tables, the absolute error is expressed in relation to the measurement range and the 
relative error in relation to the measured value.  
The total measurement error is equal to the sum of these 2 errors.
