The primary of the CTs can be between 1 and 9999A. TRIDENT 3U3I /U is calibrated to measure from 5V inputs. If you choose a lower value, the measurement precision will be slightly degraded. TRIDENT carries out different measurements according to the network selected : simple voltages : TRIDENT gives values of the voltages between phase and neutral and ...
Page 18
Overvoltage thresholds determine limits over which the rapid variations (instantaneous) should not pass, in accordance with the norm EN50160. TRIDENT records up to 1000 faults within the limit of the circular memory: when it is full, the measurement program continues, but the oldest records are replaced by the most recent.
Page 19
Duration threshold between brief and long interruptions (Threshold Ib/Il) : entered in 0,1 second. TRIDENT sorts interruptions between long and brief according to the threshold that has been programmed. All interruptions whose length is superior to this threshold will be considered long and the others brief.
Page 20
If the start date is before the present date, the program will start immediately after the last field has been validated. If the start date is later than the current date, TRIDENT will wait until this date to start the program. The device can be turned off and moved, this parameter remains in the memory.
Diagram of TRIDENT 3U3I connection on a Low Voltage three phase network with neutral, supplied by auxiliary mains 230V, with earth measurement. To supply TRIDENT by the measurement inputs, just disconnect the mains plug, and switch the Supply Selection to “Entrée measures”.
Page 22
Only the cables and the necessary connection accessories for the supply and measurement inputs must be installed. If TRIDENT is supplied using the measured voltage, the mains lead must not be connected. Only cables for the voltage measurement inputs required must be equipped with their crocodile clips.
5.2.4 Turn-On and checking connections Once TRIDENT is plugged in, it is turned-on by placing the marche/arrêt switch in position I. The red power lamp lights up and the welcome screen appears. If the measurement program has already begun (if the programmed time is passed), the welcome screen is different (see § Program in progress).
5.2.5 Starting, Stopping and Ending a measurement program. When the current time reaches or passes the program start time, TRIDENT begins the program. The red lamp blinks throughout the entire program. The welcome screen appears as follow: T R I D E N T 3 U 3 I / I V 1 .

20 ms average establishes the value of the peak of the fault, TRIDENT 3U3I archives the mean values over 1sec of the 3 voltages and the 3 currents at the instant of the beginning of the fault. These values will be memorized as the values preceding the fault, when the fault is finished and recorded.
Additionally, after the end of the fault, TRIDENT archives the mean values over 1s of the 3 voltages and the 3 currents following the end of the fault. If it is an interruption, TRIDENT defines its type as long or brief according to its duration with reference to the programmed discrimination threshold.
Every second the rolling mean value over 10 seconds of the frequency is calculated. To do this TRIDENT continuously detects zero crossings of the voltage on the phase V1, totalises the number of these zero crossings and calculates their mean over 10 secs.
5.4.8 Calculation of voltage imbalances (TRIDENT 3U3V) The rate of imbalance measured by TRIDENT 3U3V is, classically, equal to the ratio of the RMS values of the inverse and direct components. The rate of unbalance that is commonly used is defined by the ratio |Vi|/|Vd |, modulus of the inverse component over the modulus of the direct component.
CHAPTER 6 - MAINTENANCE & TROUBLESHOOTING The TRIDENT measurement device is delivered in its carrying case which is recommended for transport and storage. There is no need to open the device, it requires no maintenance and has no removable components.
TRIDENT and its accessories are supplied in a carrying case. 7.3 SUPPLIES TRIDENT can be powered in two ways, selected by a rocker switch : auxiliary supply : 230V A.C , +/-20%, 50/60 Hz, 10 VA max. supply by the measurement inputs between neutral and phase 1 : 230V A.C , +/-20%, 50/60 Hz, 10 VA max.

The « HARMONICS » application is a module that enables measurement and monitoring of the harmonic levels of the three phase electrical network. This application is loaded in the TRIDENT memory, and coexists with the basic application of TRIDENT : PERTURBATIONS i. e. the detection of faults and the recording of amplitudes over time.

8.3 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.

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.
