PORTABLE POWER ANALYSERS

MICROVIP3PLUS

POWER & HARMONICS ANALYSER

MICROVIP3 PLUS is a compact but powerful portable Power & Harmonics Analyser for both single-phase and three-phase systems.

The crisp high-contrast backlit LCD displays True-RMS values for up to 33 parameters, while the large 1MB on-board memory allows data storage over extended survey periods including waveform capture for current and voltage.
The on-board, programmable 42 columns graphic printer adds visualization of additional 156 parameters of data including V&I harmonics to 24th order with both DC component and displacement factor, and waveform/harmonic bar chart printout with manual or time-based printout.
The integrated high-speed RS232 serial port and the included PC software Microwin add further power to MICROVIP3 PLUS , allowing full graphical display and analysis of all measurement data, both with real-time connection or by downloading the internal memory. Clear, graphical reports have never been easier to produce!

PURPOSE AND USE:

The MICROVIP3 PLUS is intended for use by electrical power users who need to obtain an in-depth knowledge of their plants and systems. It is also extremely useful for plant engineers, installers, maintenance engineers and electricians in fault diagnosis and in the adjustment and repair of active electrical plant.

The MICROVIP3 PLUS allows to:

- Control loads and consumption;

- Reduce overloads and power loss;

- Check on the correct sizing of new plant entering service;

- Prevent overheating and insulation problems;

- Solve power factor correction problems;

- Identify and eliminate load peaks and associated power problems;

- Check 400 Hz n?v?l plants and 600 Hz aeronautical plant;

- Check uninterruptable power supplies with AC inputs and DC outputs;

- Measure asymmetrical signals from PWM controllers.

MicroWin

Data management software for Windows 9x and NT 4.0 developed

for MICROVIP3 Plus harmonics and power portable analyzers .

The Microwin software permits to download, catalogue and store the measurement surveys contained in the internal memory of Microvip3 Plus. Processing of such surveys is completely identical as for the numeric or waveform surveys performed by connecting the PC to the instrument in remote mode.

The software can also be used to perform waveform surveys graphically displaying voltages and current of each phase. The Harmonic Spectrum display shows the measures of voltage, current and Cosphi of all detected harmonics (0-24), both in numerical (absolute and percentage of fundamental) and bar-graph format.

While the survey is running, it is possible to display the real-time evolution of up to 4 different measures.

The user can select in any moment the number of traces to be displayed and the measurement associated to each channel.

Colors of the graphs can be personalized.

In off-line mode analysis all survey records are displayed in a spreadsheet format similar to Excel.

From the spreadsheet display the user can select up to four measures that can be represented as graphs. Measures and records to be processed can be chosen freely.

The survey configuration is easy and user-friendly. On a single window all important parameters can be set, as date and hour for the start/end of the survey, time between records, instrument setup and a descriptive label for the survey.

The scheduler window can be accessed at any time to add, cancel or edit measurement surveys.
