DEWETRON systems are used for testing all aspects of air, sea and spacecraft. And one of the most important system is the POWER itself. On larger vessels this is typically 400 Hz or even 800 Hz three-phase AC power. With DEWESoft and the POWER software option, your DEWETRON system is a complete 3 phase analyzer capable of handling any base frequency within the network, up to 800 Hz and even beyond. These are powerful systems capable of calculating not just watts and vars, but the entire gamut of power quality values, including distortion, active, reactive, apparent power, THD, phase, and literally hundreds of parameters from each 3-phase system.

It starts with the DEWETRON platform itself, which could be basically any of our models. Then the appropriate signal conditioning and A/D card(s) must be installed. Don't worry; we can configure the system for you in a few minutes based on your overall requirements.

The second part is the software, which breathes life into the hardware. The POWER option for DEWESoft adds a precision PLL that tracks the base frequency of the power with 0.001 Hz precision (yes, that's one milliHertz) in order to make the RMS and power calculations with the same exact number of samples per period, regardless of the base frequency. Even variable frequency power networks are no problem for us. You simply can't do real power measurements without constantly monitoring and adjusting the effective sample rate based on the base frequency.

DEWETRON power testing systems are in use today at Raytheon, Boeing, the US Navy on both the east and west coasts, CTC, and many, many more.
