1.4 Dangerous environments DANGER : Even though some of the systems supplied by MADE are designed and certified for installation in dangerous environments, several MADE systems are not intended for use in such environments. It is incumbent upon those who install these systems in dangerous environments to determine the acceptability of the system for its environment. Additionally, to guarantee safety, the installation of systems in dangerous environments must be compliant to the order specification of the manufacturer. Any modification of systems or their installation is not recommended and could cause deadly injuries and/or damage to facilities.

2 OVERVIEW NADIR is used for :

• The PRE-IDENTIFICATION of a cable and core in an excavation • The LOCATION of the corresponding feeder and phase in a

substation. These operations are carried out on a powered LV network under load . The operating principle of NADIR is that the Transmitter draws a complex signal down the LV feeder, with no disturbances for the connected loads. This signal will be found between the Transmitter connection point and the power source; i.e.: Substation. This signal is analysed digitally in the Receiver , which enables the user to discriminate between cables and phases. The signals used and their analysis draw on MADE SA ’s experience with the previously developed products DELTAPHASE and ZENITH. These principles are the subject of a patent application. NADIR is supplied in a carrying case holding :

• A Transmitter and connections • A Receiver with an integral transducer and two remote transducers.

GU_NADIR_V_3_20_EN 6 / 20

3 NADIR COMPONENTS TRANSMITTER :

� Integral carrying case � 1 Cable for the connection to the network

(phase-phase or phase-neutral) � 2 crocodile clips � Integral charger for the receiver � 1 mains cable (230 V ∼) for the charger � 1 link cable for charging the receiver.

RECEIVER : � Polycarbonate cased hand-held with

display screen and integral cable transducer.

� Remote transducer for cable pre-identification

� MADE-Flex (Rogowski coil) for locating the phase(s).

The charger for Receiver battery pack is integrated into the Transmitter . To charge the Receiver , connect the Transmitter to a 230 V ∼ supply, and connect the Receiver with the cable supplied. The level of charge of the Receiver is shown on the last page of the Receiver display. This reading will only be correct when the Receiver is disconnected from the charger and the charging cable.

GU_NADIR_V_3_20_EN 7 / 20

4 NADIR TRANSMITTER The Transmitter is connected, using the crocodile clips provided, either between any two phases, or between any phase and neutral on the feeder, downstream of the point of interest.

THE TRANSMITTER AUTOMATICALLY ADJUSTS TO THE VOLTAGE SUPPLIED .

� Turning ON the TRANSMITTER :

• Connect the 2 crocodile clips between PHASE and NEUTRAL or between PHASES, depending on the kind of network (The fan starts)

• Pressing the push button once, located in the "TRANSMITTING" area, starts the emission

• The yellow LED flashes showing the going-on emission • Turn down the cover, do not try to lock it • Start measuring with the RECEIVER.

A LED indicates the presence of the supply (230 V or 400 V). The Transmitter is started by switching it ON, and a flashing green LED indicates correct operation. In the presence of an internal fault, the red FAULT lamp will light. Should this occur, turn OFF, check the connections and re-start. If the fault persists, contact : NIS, A. T. M. S. or the manufacturer. The NADIR Transmitter monitors its internal voltages, the cooling fan and the overall operation. So as to improve reception, try to connect the Transmitter as close as possible downstream of the point of interest.

� Stopping the TRANSMITTER :

• Press the push button, used to turn ON the Transmitter. • The yellow LED stops flashing, the fan is still in operation • Disconnect the crocodile clips from the network, the fan stops.

5 NADIR RECEIVER The Receiver assembly includes :

� The Hand-held with control buttons and display with an integral transducer � The Cable Pre-identification transducer � The MADE-Flex Rogowski coil transducer for Phase identification.

Battery pack : The last menu page indicates the level of charge of the integrated battery pack. This reading will only be correct when the Receiver is disconnected from the charger and the charging cable. To recharge the battery pack, connect the link cable to the charger in the NADIR Transmitter and connect this in turn to the mains (230 V∼). Receiver battery life : 5 hours in normal use. Charging time : 10 hours (when completely discharged). When the Receiver detects a charge level of 20 %, the display indicates this and turns OFF. Then, recharge the Receiver . Turn-off after 5 seconds.

6 USING NADIR RECEIVER

� To start the Receiver : Press ON The software version number and the telephone number of MADE-SA are shown. � To use with the cable pre-identification Transducer

• Connect this Transducer • Place the Transducer on the cables, one by one to find the highest signal.

� To use with the integral Transducer

• Do not connect a Transducer to the Receiver • Place the back of the Receiver on the cable and proceed as above.

� Menu :

• Press VALID to enter the configuration page: Backlighting ON - OFF Memo Max ON - OFF

• Memo Max : display the largest signal value in the series of measurements, in addition to the latest value.

After configuration, press SCROLL .

Press VALID :

• The bar graph continuously indicates the signal level measured in percent • The signal reading is updated every 2 seconds.

The measurement is instantaneous and in real time. Press VALID and SCROLL :

� Menu IDENTIFICATION : for a more precise discrimination between cables and phases :

The measurement is made with more sophisticated algorithms in order to better identify the transmitted signal, and integrated over 5 seconds. The SEARCH function enables quick location of the cable sought. The IDENTIFICATION function confirms this for cables and phases with more precision and leaves the signal level value on the screen together with the highest value in the sequence if the Memo Max function is activated.

7 NADIR OPERATION

� " CABLE PRE-IDENTIFICATION " function :

There are two options :

• The remote Transducer is placed on the cable • Or just the Receiver , using the internal Transducer .

The measurement is carried out at the point of interest. Since the conductors are twisted in the cable, and the modulation is between one phase and neutral or between 2 phases, move the Transducer along or around the cable to seek the best signal. This operation is first done in SEARCH mode, which gives an instantaneous measurement (acquisition time ∼ 2 seconds). During the acquisition, hold the transducer still. When a significant signal is found, change to IDENTIFICATION mode, which gives a measurement integrated over 5 seconds. As an indication, drawing on our experience, the minimum values found on the correct cable are around 35 to 40 % (according to the network and it’s load). In ideal circumstances, the received level is from 70 % to 90 %. On the "wrong " cables or phases, the signal is < 10 %.

� In " PHASE IDENTIFICATION " mode :

• Connect the « MADE-FLEX » (Rogowski coil) Transducer to the Receiver The Receiver differentiates automatically between Transducers. Note : Do not put this Transducer around the cable or the screen, only the Phase to be measured, or only the Neutral of the feeder, depending on the Transmitter connection. • Close the « MADE-FLEX » coil.

� The menus SEARCH or IDENTIFICATION are used as above :

As an indication, the minimum levels observed should be between 30 % and 100 % (depending on the network and loads). On the "wrong" cables, the signal is < 10 %.
