Handheld power-monitoring instruments

February 2004 Electrical Power & Protection

Spescom MeasureGraph is offering three new handheld power-monitoring instruments from Dranetz-BMI. All three products incorporate a colour touch screen, 'super smart' automatic set-ups and an enunciator 'report card' that instantly characterises power quality events. The enunciator collects, analyses and tabulates power-monitoring data as pass or fail. Users can access more detailed information by touching the intuitive screen.

The new instruments have been designed to meet the needs of all power professionals - from the novice technician tasked with troubleshooting a power quality problem, to the expert power engineer responsible for instituting a reliability-centred preventive maintenance program throughout a facility's power infrastructure.

Equipped with eight independent channels, the affordable three-phase PowerGuide 4400 is reported to be the only advanced power-monitoring instrument to incorporate a colour touch screen into its lightweight design. Automated set-ups provide instant detection of circuit types and configurations, ensuring that the instrument is ready to successfully collect data. Users can select the length and mode of data collection, including troubleshooting, data logging, fault recording, inrush, power quality surveys, equipment performance testing, energy studies and load balancing.

Setting a new standard for enhanced performance and ease of use, the PowerXplorer PX5 delivers a range of advanced features in addition to those standard in the PowerGuide 4400. With high-speed sampling and data capture, this 8-channel workhorse simultaneously captures and characterises hundreds of parameters, using a range of standard and customisable operating modes. The unique measurement capabilities of the PowerXplorer include capture of low-medium-high frequency transients through peak, waveshape, rms duration and adaptive high-speed sampling, AC/DC measurement for events lasting from a microsecond to an hour, and harmonics/interharmonics to the 63rd.

The 3-phase, 8-channel PowerXplorer PX5-400 provides the full range of advanced monitoring and measurement for 400 Hz applications as well as 50/60 Hz. Designed specifically for military, shipboard, aerospace and other 400 Hz applications, the instrument contains the same advanced feature set as the PowerXplorer PX5, including advanced data characterisation, cross-triggering and the measurement of distortion parameters.
