generated.
Danger – Never connect the power supply cables to a line
before connecting to the equipment.
Raptor
12
Danger – When conducting resistance tests, be sure that the
circuit is earthed to some point. If it is a switch, one of the
sides must be connected to earth and the switch must be
closed.
Danger – Before injecting current on the primary of a current
transformer, be sure that its secondary is closed. Otherwise,
high voltages may appear.
Danger – Never operate with the system if you observe
severe damage to it or humidity on it.
Hazardous situations for the Raptor system
Caution – In systems with Raptor-
SL units, when preparing to
conduct injections by pass-through turns, be sure that all the units
are powered.
This is necessary so that the thermal protection
systems work correctly.
Caution – Do not inject using the pass-through turn simultaneously
with the auxiliary output.
Caution – Do not try to lift the equipment using the fold-down
handle. Instead, use the top handle.

INTRODUCTION
The Raptor marks the difference with respect to any primary injection testing equipment
that currently exists. Its innovative design and cutting-edge technology allow substation
commissioning and maintenance tasks to be carried out more efficiently, given that the
concept of manageability is taken to extremes that were previously never possible to
reach.
With the Raptor, SMC opens the door to a new generation of testing equipment based
on the formula of innovation, designed with and for the user and endorsed by more than
25 years of experience developing practical, affordable and long-lasting solutions for its
customers around the world.
As high-current injection equipment, the Raptor’s design fulfils three fundamental
objectives: 1) being able to bring equipment as close as possible to the device under test,
2) controlling current automatically and 3) only requiring one person.
The basic system (C-05) or ‘master unit with console’ is extraordinarily compact and
manageable equipment, with a touch-screen console that allows making precise
electrical measurements and conducting multiple types of testing, including high-current
testing, for which it uses an elegant implementation of the secondary pass-through
technique. A single conductor passes through the equipment from one side to the other
in order to transmit the current to the object being tested, connected at its two ends. This
saves preparation time and eliminates power losses. The wave shape, of variable
frequency, is generated digitally and is extracted through a 3-kVA power amplifier with
extreme precision and control, insensitive to the variations that might occur in the load
and even in the power supply voltage.
The Raptor slave units, externally identical to the master unit, allow increasing the
injection power in 5-kVA steps just be aligning them with the master and passing the
injection conductor through the entire assembly. A sophisticated power management
system, supported by a robust infrared communications channel, allows managing up to
five Raptor units as if they were a single unit and without having to connect them to each
other, thereby reaching an injection power of over 18 kVA and a current of up to 15,000
amperes. In addition to all this configuration flexibility, there is the possibility of increasing
the applied voltage simply by looping the conductor around the equipment several times.
The Raptor is managed using a small touch screen, which attaches magnetically to steel
surfaces for greater convenience. Updateable by a direct connection to Internet, this
powerful, multilingual controller also stores testing templates pre-configured at the
factory, in addition to those defined by the user, as well as the testing results. Its software
includes an assistant to determine the Raptor configuration and the necessary cable
characteristics for conducting a specific test, even before leaving the office.

HOW TO CONNECT THE SYSTEM
The Raptor system will be composed of at least one Console (Raptor-HH) and one
Master unit (Raptor-MS). Depending on the configuration that you have acquired, you
can also align up to 4 slave units (Raptor-SL).
To connect the system, you must first set up a power supply line with sufficient power/
cross-section to cover the power that your load requires, plus the losses of the generator.
Even though this is difficult to know in advance, you can take into account the maximum
admissible consumption per unit:
Raptor-MS: 18 A permanently, 36 A for 3 minutes and 72 A for 3 seconds.
Raptor-SL: 26 A permanently, 52 A for 3 minutes and 104 A for 3 seconds.
You must keep in mind that the Raptor gives maximum power when fed at 240 VAC,
measured at the start of the supplied power supply cable. To the extent that this voltage is
less or drops during the test, the maximum current or maximum voltage will also drop.
Positioning of the equipment
When preparing to inject current using the ‘pass-through turn’, you must align the Master
case with the Slaves.
This makes it easier to pass the cable through the hole of each unit and allows the
infrared communications channel of the Raptor units to work correctly (this
communication, in both sides of units, is designed for being viewed directly and at a
distance of less than 1 meter).
Conversely, if you are going to use the auxiliary Voltage/Current output, be sure that
there is no closed pass-through turn.
Do not use the auxiliary output at the same time as injection by
pass-through turns.

Make the connections
Before continuing, be sure that the main switches of each unit are in the Disconnected
position.
Connect the earth cables present on the power supply
cables of the Raptor-MS and Raptor-SL units to each other
and to an adequate earth.
Make the necessary connections, both injection and measurement. These connections
will vary according to the nature of the test, which in some cases will be detailed later in
this manual.
Connect the Console (Raptor-HH) to the Master case using the cable provided.
Now connect the Raptor-MS and Raptor-SL units to the power supply. Do not make this
connection permanent, due to the fact that if several units are combined, the system
requires that all the units be connected with the same polarity. There is no need to be
concerned, because if the polarity is not the same, the system will detect it and will
indicate on which ones the polarity must be changed.
The polarity is the position of the line and the neutral on all the units. The polarity of
reference will be given by the polarity of the Raptor-MS unit.
You will not be able to work with the equipment until all the units
are connected with the same polarity.

TURNING ON THE SYSTEM
Raise the main switches of each one of the units forming your Raptor system. The correct
polarity and power supply status can be checked through the indicators on the control
panel of each unit.
AC in
green LED must remain On from the moment you power up the unit with the circuit
breaker. Otherwise should check the line power, breaker, fuses etc.
Fault
yellow indicator, when remain On, indicating a fault in one of the machine's
internal supplies or line level too low for proper operation of the unit.
After turning on the system, it begins with system identification by the Raptor-HH unit. The
identification screen graphically shows how the system is connected. If any unit has been
connected erroneously, with the polarity of the line inverted or the polarity of the unit
inverted, this will be shown in the system’s detection window. This error is also indicated
by flashing of the Fault indicator on the case where the polarity is inverted with respect to
the master case. Any connectivity error will not allow working with the system until the
correct connection is made.

With the system detected as stable, all the units comprised in the
same display their connectivity indicators (blue indicator) as permanently
illuminated, thereby indicating that they were detected and recognised by the
system. If this were not so, the unit would be flashing and would not be
recognised by the system.

state remain at power, before any alarm (thermal, communications, power supplies,
overhead, etc..) And at a reset.
Trip Ovd
yellow indicator, (only present in the unit Raptor-MS) indicates an overload on
the output, this can be due to various causes such as load value too high etc.. This
indicator will be deleted when activating power and in case of persistent overload it will
activate again.
Trip Th
yellow indicator, indicates thermal overload in the unit. While this indicator stays
On will not be possible to power up the output. When the unit returns to the proper
working temperature it will deactivate.
In Raptor-MS unit, there are two
OUT
red indicators, one on the main panel and one on
the expansion panel. The first is general and indicates that the power is on, regardless of
the mode of generation selected. The one in the expansion panel indicates that the
auxiliary output is active.
In Raptor-SL unit, there are two but in this case indicate which of the two internal
transformers are active.
With the system stable, the identification window reports the detected system according to
the number of units comprised in the system (Raptor-C05, Raptor-C15, etc.).
The only part of the system that cannot be detected is the number of turns that form the
pass-through winding. Using the system detection window, you will have to enter the
number of pass-through turns with which you will work. If you do not yet know or are
going to work with the auxiliary output, validate the existing number. You can change it
later. Press the dial to accept.

AN INITIAL VIEW OF THE CONSOLE
The status LEDs
The alarm LED (yellow) will indicate the presence of an alarm in the
system. There are two types of alarms: critical alarms and non-critical
alarms. Critical alarms are those for which the system prevents power
from being supplied, such as an overload of the output, a thermal overload, etc. When
such an alarm occurs, the LED will remain illuminated permanently. Non-critical alarms
are those that are not destructive, and it is possible to continue working with the
equipment, such as range saturation of the external meters. When this type of alarm
occurs, the LED will remain flashing. Activation of either type of alarm will be
accompanied by three beeps.
The power LED (red) will indicate the activity status of the output power.
The connectivity LED (blue) indicates that the Raptor system has been detected and is
stable when it is illuminated permanently. When this LED is flashing, it indicates that the
Raptor system is not stable with respect to connectivity.

When Dry contact mode is assigned, if the voltage applied to the binary input exceeds
18-20 V DC the machine is protected changing mode automatically to Vmode high (15
V). Upon this protection, you are warned by alarm indicator overload but it is a
momentary display, as when it changes to voltage mode, the alarm disappears. For this
reason, the EB status indicator is displayed flashing to be aware of the event. To remove
this blink situation, you must enter the EB setup window and validate the new settings by
clicking OK.
Stop condition indicator.
It is activated when the selected condition for stopping the test
has been met. The indicator lights up green when activated.
Otherwise, it lights up white. When the stop condition is
activated, all other visible meters go to the Hold status.
To configure the stop condition, tap twice on the indicator or
select the
options button and then the Stop Conf. button.
Hardware meters
A maximum of four meters can be displayed.
To configure the hardware meters, tap twice on the meter control
or access configuration from the meter selection window. The phase meters do not have
a settings screen.
Calculated meters
There is no limit to the number of calculated meters that can be

MAKING THE FIRST CURRENT INJECTION
Caution – If injection is going to take place through the auxiliary
output, it is essential to leave the pass-through winding in an open
circuit.
After making the connection sequence as
explained in the chapter on “How to connect
the System”, now the load must be
connected.
The minimum required Raptor System adapts
to each load-environment situation when it
injects on its pass-through winding. While the
number of Raptor units used, the number of
pass-through turns, the length and crosssection of the pass-through cables and the injection range can vary, there is an optimum
combination for a minimum Raptor System. The majority of the application’s controls
open up a window, thereby allowing the controls to be configured by tapping twice on
them.
Important – The most powerful configuration (NOT the optimum
configuration) for a desired current is obtained:
1. By using the greatest possible number of Raptor-SL units.
2. By increasing the number of turns to the maximum, as long as the
maximum selectable current on the Raptor-HH continues to be
greater than or equal to the desired current.
3. By maximising the cable cross-section, thereby attempting to
occupy the largest possible space of the pass-through hole.
4. By minimising the cable length and the intermediate connections
to the load.
5. By braiding the cable both to and from the load.
Important –
The “Current calculator” is a utility included in the
Raptor-HH (also available for a PC), which helps to estimate an
optimum Raptor System for each case.
