The Raptor System
Multifunctional Primary Testing System
The Raptor is a smart test system designed as the ultimate solution for the main primar y test applications
required in the commissioning and maintenance of substations, marking the difference with respect to
existing equipment now being used. This new generation of Primary Injection Test System makes primary
testing easier, faster and more convenient.
The system consists of a Master unit which can be upgraded with up to three Slave sets which add
further power capacity to the system. The user is not limited to the power initially determined. In case
of more power required, Raptor sets can be added, or what is also very important, be left behind when
not needed.
In comparison with the big and heavy traditional variac-based equipment, the Raptor is designed
incredibly smaller and lighter than its predecessors, combining a revolutionary high current generation
technology, DSP based, with an automatic smart control, in a really transpor-
table set, less than 35 Kg and able to inject up to 15,000 A.
An additional advantage to the easy transpor t is that sets can be much clo-
ser to the devices tested, reducing the length of cables, and a significant
decrease in power losses by eliminating intermediate connections, thanks
to the new loop-through concept. The sets have in the middle a hole
to pass through the cables which are connected to the
load, forming in this way the injection circuit.
Efcient Power
The modern high-tech design of the Raptor system enables the
highest level of injection capability in terms of power and duty cycle, with an ease of use so far unknown in this type of
equipment. A touch-sensitive console allows the user to fully monitor and control the test process, including the storage
of results and test configuration tools.
The Raptor system provides automatic regulation of the magnitude to be injected, being stable regardless of the load or
power supply changes. Current output range is adjusted at all times according to application, taking advantage of the
modularity and versatility of the concentration of measurement and control functions in the Raptor Master unit, with a
unique capacity to adjust the voltage and current required through the number of spire turns used.
The Raptor also includes a power ful measurement section, ex tending the number of testing applications.
Raptor system includes factory configured tests, to automatically per form a large amount of the most common testing,
just by selecting the appropriate template and start the test. The user has also the possibility to easily make or modify
test templates.

The Raptor System: Applications
The Hand Held Control Unit, RAPTOR-HH, is the user-friendly interface from which the operator remotely controls and
monitors all the test process. The Raptor HH detects and configures the master and slave units automatically.
It provides an intuitive TFT touch screen, visible even in direct sunlight, with a wheel-and-click control that combined
with the existing test templates makes the test configuration and execution task extremely easy and fast.
The unit saves all the test configurations and results on its own memory, which can be further downloaded to an
external computer through USB connection and the RaptorSync software. This unit only weights 0.4 Kg and it is
developed with an ergonomic design optimized for correct handheld use, and nonslip laterals for a safer grip.
The Raptor HH is connected to the Master through a 5-meter cable that allows the user to stay at a convenient location
while the test set is working much closer to the load. For ex treme cases, a 4-meter extender is available as an optional
accessory. The console’s back is magnetized, which allows the user to snap it quickly and safely on any iron surface for
a more comfortable operation.
Other advantages are: data storage and reporting, configuration assistance, software upgrades by internet, simplify
and reduce testing time, easy touch/turn operation, maximum test accuracy.
Test Templates allows the user to just select the appropriate template and start the test. Most common tests available
are: Overcurrent relay, MCB/MCCB, CT Ratio/Phase/Burden, CT ratio/phase with voltage, VT ratio/burden/phase,
Rogowsky CT, PT, contact Resistance, Ground Grid, CT magnetization curve and Knee point, Pulses, Recloser, etc.
The Raptor Current Calculator is included as standard in the Raptor HH console and can also be installed on a PC. It is a
simple to use yet sophisticated tool that allows the user to quickly define the Raptor configuration and the number and
type of cables required as minimum to successfully accomplish a specific high current job, even before leaving the of fice.
APPLICATIONS
The combination of mobility, adaptability, automatic current regulation, high-tech, ease of use and versatility makes
the Raptor the best system available in the market for all major primary injection testing applications in and around
substations and power plants:
Primary Current Injection Testing
Primary Injection Testing is essential in commissioning and verifying a protection scheme. The secondary injection
test does not check all the component s in the system, as it cannot provide the condition of the overall protection
installation, whether CTs have the correct ratio or polarity, or whether the secondary wiring is correct and serviceable,
and it does not mimic the operating conditions in service. Therefore, the Primary injection testing is the only way to
prove correct installation and operation of the entire protection scheme, and the Raptor has been specially designed to
meet all primary testing needs.
The Raptor´s variable output frequency extends the primary testing diagnostic with frequency sweep, offering test
frequencies different from the mains frequency, and thus enhancing its electrical testing capacity. Primar y Test involves
the entire circuit; current transformer primary and secondary windings, relays, trip and alarm circuits, circuit breakers
and all wiring are checked. Primar y injection tests are carried out after secondary injection tests, to ensure that
problems are limited to the V T’s and CT’s involved, circuit breakers, plus associated wiring, all other equipment in the
protection scheme having been proven satisfactory from the secondary injection tests. Hence it is often the last tests
performed in the commissioning and maintenance process, or after major modifications have been carried out, and
also as an invaluable aid to faultfinding.
