• 3-kVA Primary Injection Test System up to 9,500 A
• The smallest fully functional Raptor configuration
• Automatic amplitude and phase angle regulation
• Power-on, injection, protection, and communications
• RS-485 connection for touch-screen console and other compatible devices.

Composed by a Raptor master and a console, the Raptor C-05 is the smallest fully functional Raptor configuration. It is adequate for numerous test and measurement functions involving medium- to moderate current and where the distance to the tested device is not a factor, as when testing MCBs or medium-sized MCCBs. The Raptor C-05 can comfortably work in the range of 500 A using a narrow connection (around 25 sq. mm), which also enables the user to make two or more turns through the pass-through hole to increase the compliance voltage when testing on higher loads.

The output frequency can be varied between 20 and 400 Hz, which allows the filtering of undesired interferences from the surrounding high voltage when doing precise, small-magnitude measurements.

The auxiliary output, binary input, and measurement functions are automatically configured by the standard set of test templates, so the user only needs to enter one or two parameters to easily test a transformer, a circuit breaker or a protective relay to mention just a few examples.

This functionality is standard in the Raptor master, so it is available also in more powerful Raptor configurations.

The Raptor MS is the master unit of any Raptor configuration. It provides the connection for the touchscreen console and can be used as stand-alone for primary test applications that do not require extremely high currents. When slave units are added, the MS will detect them automatically over the infrared link and will accommodate the system’s parameters with no intervention from the user.

The Raptor MS features a digital waveform generator driving a 3-kVA switching amplifier designed for a maximum 15 kA throughput. The amplifier’s output is applied to a toroidal winding that surrounds the Raptor’s pass-through hole internally. A concentrically aligned Rogowsky sensor measures the current inside the hole, providing continuous feedback to the amplifier for dynamic compensation of load or supply variations with an accuracy better than 1%.

In addition to the 20-400 Hz variable frequency and to the high current output which is common to all Raptor units, the MS features a 2000-VA auxiliary output that supplies up to 35 A in current mode and up to 200 V in voltage mode, as well as measuring inputs for external AC or DC, including a high sensitivity 0-3 V input. As an alternate method for trip detection, a binary input is also provided to monitor the activity of a dry contact or energized point in the object being tested. The input is sensitive to voltage for automatic mode switching. Finally, the MS includes a system expansion connector for future developments.

The factory- or user-defined test templates pick up only the necessary among all these test and measurement resources for each type of job, so that the user only needs to select a template from the menu and start the test. The standard list includes templates for circuit breakers, current transformers, trip testing, low impedance, ratios, reclosing, and many more. This approach provides a cleaner screen layout because the user is presented only with the data that is needed for each specific task.

All Raptors are powered by single-phase 240 VAC 50/60 Hz and include an automatic thermal-magnetic cut-off switch for protection against internal failures. A protective nylon cover featuring a generous pocket for accessories is also included as standard. This cover leaves the foldable handle and the wheels uncovered for easy transportation and can be quickly removed for working.
