CHAPTER 1 - TRIDENT OVERVIEW
1.1USING TRIDENT
The TRIDENT range includes the following products:
TRIDENT “Blind” including:
Trident 1U
Trident 1U1I
Trident 3U
Trident 3U3I
TRIDENT standard:
Trident 3U
Trident 3U3V
Trident 3U3I
With a harmonic option on the TRIDENT 3U3I.
Remark:This note describes the use of any product in the TRIDENT range.
The display functions and use of the keyboard that are described here do not apply to a
“Blind” TRIDENT.
Similarly, descriptions of the measurement functions of triphase units are to be considered in
monophase for versions 1U and 1U1I.
TRIDENT is used to perform measurement programs on three phase & single-phase low voltage (400V) and
medium voltage (11 or 20kV.) electrical networks using measurement sensors.
The device has only low voltage inputs.
TRIDENT 3U3I /I is intended for use with current clamps having a current output of 1A or 5A.
TRIDENT 3U3I /V is intended for use with current clamps having a voltage output of 1V to 5V.
During a program, it records:
Voltage faults, including those on the Neutral/Earth,
A running record of the RMS values of the voltages and currents, as well as the total active power,
The durations of frequency out-of-limits (measured on the phase 1 voltage input),
The durations of out-of-limits of the mean values of the voltages,
Five date stamped maxima of current in 1 sec. values and P in mean values (for the product of U & I).
TRIDENT has a local user interface, consisting of an LCD display of 4 lines of 20 characters each and 4
buttons (except, of course, for the « Blind » versions).
Communication with a PC is made via a series connection RS232 (RS485 is optional). The WINTRID PC
software is a necessary complement for TRIDENT which enables the study and analysis of the measurements
made by the equipment.

GU_TRIDENT_V_1_20_EN 5/47
1.2 GENERAL DESCRIPTION
1.2.1 Functions
TRIDENT is a portable recorder, light and field-tested, which records & analyses the voltage,
current and power on single and three phase electrical networks.
TRIDENT can:
Measure and assess the voltage quality according to the EN 50160 Standard: "Voltage
characteristics of the electricity supplied by public distribution networks ", notably:
Slow voltage variations,
Brief overvoltages,
Brief dips,
Brief & long interruptions,
Frequency variations,
Overvoltages between neutral & earth (except monophase products).
Record the evolution of the continuous measurements of the 3 currents and the 3 voltages taken
simultaneously at the same measurement point,
Carry out an analysis of the active power consumption at this point of the network.
TRIDENT is supplied with the WINTRID display and configuration software, which runs on the
WINDOWS 3.11, 95, 98, NT and XP versions.
WINTRID enables :
The configuration of the computer,
The configuration of TRIDENT,
The consultation of the instantaneous measurements,
The sampling and graphical representation of the slow variations in voltage, current and power
superposed on the voltage events,
The preparation of a list of all events and their characteristics,
A statistical analysis of the events,
Rapid and simple printing of reports in colour,
The transfer of data to other applications (spread-sheets, word processing...).

GU_TRIDENT_V_1_20_EN 6/47
1.2.2 Recordings
The quality of the 3 voltages, either simple (i.e. Phase to Neutral in a star network) or line (i.e.
between phases in a delta network), is continuously monitored by TRIDENT.
Slow Variations of Amplitude:
The number of times the mean voltage passes the high & low thresholds is totalled.
Rapid Variations of Amplitude:
TRIDENT can sense and record any voltage variation with a time resolution of 2ms.
TRIDENT records 3 types of faults according to the threshold passed by the voltage:
overvoltages,
voltage dips,
Long interruptions,
Brief interruptions.
A minimum duration threshold, programmed by the user, is used to avoid recording very brief
events.
A voltage fault is recorded with:
start time & date,
duration,
type,
phase,
the mean voltage during the fault,
a 10ms peak voltage during the fault,
the 1 second values of the 3 U (or V) and 3 I before the fault,
the 1 second values of the 3 U (or V) and 3 I after the fault,
Overvoltage between Earth & Neutral :
The voltage between neutral & earth is measured continuously over 20ms rolling each 2ms.
Crossing a threshold starts the recording of an Earth/Neutral overvoltage, having the same
characteristics as for a voltage fault.
Frequency monitoring :
The frequency is continuously measured in the form of a 10 second mean on the phase 1 voltage.
Crossings of a high or low threshold are totalled.
Power and Current Maxima:
The 5 highest values of the currents (1 second mean, all phases together) are recorded & dated.
The 5 highest values of the active total power are recorded & dated.

CHAPTER 3 - TERMINOLOGY
3.1ABREVIATIONS
HTA: high voltage used for electrical supply, with anominal RMS ranging from 1kV to 50Kv
HTB: high voltage used for electrical supply, with a nominal RMS superior to 50kV
LV : Low Voltage electrical supply, with a nominal RMS value ofless than 1kV.
TRIDENT only directly measures LV with a the nominal RMS value of less than 400V.
VT : Voltage transformer, placed between the high voltage to be measured and the TRIDENT inputs.
CT : Current transformer. In this document clamps with current outputs (for TRIDENT 3U3I /I) and
clamps with voltage outputs (for TRIDENT 3U3I /U) have the same abbreviation.
3.2GLOSSARY
Voltage dips: rapid and temporary voltage drop measured below the programmed threshold,
followed by a re-establishment of the voltage, or an interruption.
Overvoltage: temporary voltage increase, slow or rapid, measured above the programmed threshold.
Brief interruption : disappearance or large voltage drop measured during a brief instant. According to the
EN50160 standard, a brief interruption is less than 3mn.
Long interruption : disappearance or large drop of voltage. According to the EN50160 standard, a long
interruption is over 3mn.
Rapid Variation, voltage fault : abrupt variation of the voltage RMS value measured over at least
one cycle (rise, dip or break) followed by a re-establishment of the
voltage or a change to another type of rapid variation. A rapid
variation over the detection thresholds of TRIDENT is considered as
a voltage fault.
Slow Variations: variations of the mean RMS values of the physical parameter measured (voltage,
current or power).

CHAPTER 4 - INSTALLATION & START-UP
4.1 1st START-UP
4.1.1 Connection to the TRIDENT supply
On reception, TRIDENT should be connected close to the PC which will serve as the workstation
for the recordings, in order to open communication with the WINTRID software.
For the 1st start-up, it is sufficient to insert the plug of the power cable supplied with the equipment
in the auxiliary power socket and the other end in the mains 50Hz, 230V A.C.
The supply mode selected must be Auxiliaire 230V  ,10VA max.
On site, it uses the voltage measurement inputs as a source of supply. This supply option is
explained in paragraph 5.2.3 Installation on site and in this case the switch should be in the position
Entrées mesures N-V1 230V  ,10VA max.
4.1.2 Turn on
The device is turned on by switching the marche/arrêt switch to position I. Turn the device
offsimply by inversing the switch or in the absence of an alternative supply when the internal
battery is discharged.
Upon start-up, the red light is lit and the screen shows :

This screen also indicates the internal date and time of TRIDENT. This time can be slightly
different from the correct time because of possible drift during storage.
Pressing the button VALbrings up the main menu.
4.2 GENERAL RULES FOR THE USE OF THE USER INTERFACE
On the front face of TRIDENT is a 4 line, 20 character display, as well as a 4 key keyboard:
+(plus),
-(minus),
(left arrow),
(right arrow, VAL)
This group is enough to configure or operate TRIDENT.
All the keys autorepeat if held down.
Generally :
The keys +/- are used to move an arrow on the screen, or to modify the value of a figure being entered
(underlined by the cursor).
The key can, depending on the position of the cursor, move to the digit or field following, or
validate a page and move to the following page.
The key can, depending on the position of the cursor, move to the preceding digit or field, or return
