 DETAILLED DESCRIPTION 

 

During  a  measurement  program,  TRIDENT  H  acquires  the  input  signals  :  3  voltage  phases  and  3  current 
phases. From these values, it calculates the amplitudes of the 40 first harmonics on voltages (simple or line) 
and  currents  every  second,  as  well  as  the  THDs  and  instantaneous  TDDs  for  each  phase.  These 
measurements are then integrated over the period configured by the user in order to obtain the mean values.  
The  mean  values  of  the  first  24  harmonics  (nos.  2  to  25)  are  compared  individually  to  the  programmed 
thresholds. When there is a threshold crossing, the corresponding counter is incremented. There is a total of 
144 counters (24 counters for each of the Us and Is).  
In the same way, the mean values of the THDs and TDDs are compared to the programmed thresholds, and 
the corresponding counters are updated. There are 3 counters for THDs and 3 counters for TDDs.  
The mean values of the 3 THDs and the 3 TDDs are stored in recorder which capacity depends on the chosen 
integration period :  

 

28 days with a period of 10mn,  

 

a little less than 3 days with a period of 1mn.  

Values of  the  6  signals  are  also  stored for 3  harmonics  chosen by  the  user. The  memory  capacity  for the 
harmonic depends on the integration period chosen :  

 

8 days with a period of 10mn,  

 

more than 19 hours with a period of 1mn.  

All these memories are circular, i.e. when the memory is full, the oldest records are replaced by most recent.  
Finally,  TRIDENT  H  integrates  the  mean  values  of  harmonics  and  the  THDs  and  TDDs  over  1  week, 
calculates and memorizes this weekly mean. Thus the weekly mean of the first 4 weeks of the program can 
be obtained.
