Massive use of digital technology and innovative design turn the Raptor system into the most portable primary test set available, at a very attractive price.
The simplest Raptor configuration gathers a comprehensive set of resources and test functions in an ultra compact, remarkably portable 77-lb (35 kg) body: master unit, detachable touch-screen console, voltage and current measurement inputs, dual voltage / current test source, binary input, and a 3-kVA digital amplifier for a maximum 9,500 A current injection with variable frequency. A large diversity of test jobs can be accomplished, including circuit breaker and re-closer testing, ground grid integrity verification, transformer saturation analysis, burden and ratio measurement, and more.
For high current applications, the Raptor implements the ‘pass-through secondary’ technique, with a centered hole that confers to this product a unique personality. You only need to drive the current conductor through the Raptor and attach both ends to the device under test. Multiple cables can be used in parallel to increase the effective cross section, and the compliance voltage can be easily multiplied by just doing multiple turns around the unit. If additional power is required,5-kVA slave units can be added for up to a total 18 kVA and a maximum 15,000 A injection. These units communicate with the master Raptor via an infrared link, so no physical interconnections are required. An integrated software calculator allows determining the equipment and cabling required to attain a specific amount of current easily.
