Ranger PM7000 Power Quality Recorder
Outram Research has enhanced the functionality of its market leading Ranger PM7000 Power Quality Analyzer, the industry’s only Cat IV 600V Phase A-powered analyzer, with the addition of support for capture of IEEE 1459 and IEEE 100 parameters. The new functionality allows users to more effectively measure useful power, fundamental reactive power and distortion power to help resolve a wide range of power quality problems.
IEEE 1459 is an emerging standard that defines new formulae providing detailed information on the power that is being consumed. Uniquely the standard defines a rigorous measure of distortion power, a measure of the power consumed due to imperfections in the current and voltage sinusoid. Many modern electronic products – particularly low-energy florescent light bulbs – do not draw current in a sinusoid. These devices pull small spikes of current at the peak of the voltage sinusoid, distorting both current and voltage waveforms on the supply network, which in turn can lead to more power being wasted in motors and other appliances that require sinusoidal supplies.
In addition to the new functionality, the PM7000 measures power quality to the IEC61000-4-30 standard, harmonics to IEC61000-4-7, and flicker to IEC61000-4-15;
Uniquely all Outram power quality analyzers offer Outram’s patented single-cycle Adaptive Store that ensures detailed capture of intermittent power quality problems over long recording periods. In the PM7000 this operates on up to 32 channels, selected from any of the available parameters; and in addition approximately 500 general parameters are recorded automatically at (selectable)
Existing PM7000 units can be upgraded in the field to add the new functionality with a firmware update available on request from Outram Research.
