The MODEL 108A UNIVERSAL HIGH PRECISION POWER ANALYZER measures 280 electrical quantities on every phase. Energies, harmonics, motor- and transformer values, power sums, power ratios, analog- and frequency inputs can be displayed, or read via interface at any time.
Upgrading the instrument is feasible due to modular concept at any time.
This is the latest instrument which has joined the Infratek Power Analyzer line. It is reliable, simple and intuitive to use and presents countless features. Highly accurate measurements for test and development of power electronics in fields such as: electric motors, simultaneous measurement of two synchronous motors, inverter drive systems, automotive, solar / wind energy, transformer testing and many more.

Four measuring functions:
Standard Measure Mode:
In the Standard Measure Mode 280 quantities per phase are measured without gap and are continuously updated. Values can be displayed on four display pages, can be saved in interna memory, or can be transferred via Interface to a computer. The display shows voltage, current, and power wave forms. Harmonics and bar graphs can be viewed on 5 pages. Two electric motors can be tested simultaneously. External Speed and torque inputs are optionally available. Transformer values are implemented too.
Logging Measure Mode:
This measure mode is suitable for very fast measurements or for long time averaging of data. It is possible obtaining 6 datasets of a 6-phase instrument within 20ms or 6 datasets per 10 minutes.
From every phase you obtain 8 values: frequency, rms current, rms voltage, power, power factor, apparent power, energy Wh, and apparent energy VAh.
Cycles: For Logging Measure Mode set Cycles 1 to 32000. Defines the measurement duration per measurement set. Use pop-up number pad. Format 160.
Transient Measure Mode:
You can catch current-, voltage-, and power wave forms in a start-up on transient mode up to 6 phases simultaneously or you can view all the wave forms at a critical operating point. Sections of the wave forms can be expanded by simply
touching one of the 4 “Zoom Sectors”.
Transient ID: Set it to 1, 2, 3, 4, 5, 6, or 7. The transient ID determines the measurement duration after start. Transient ID Measurement duration: 1 {0.25s}
2 {0.5s} default, 3 {1s}, 4 {2s}, 5 {4s}, 6 {8s}, 7 {16s}.
Power-Speed Measure Mode:
This measure mode analyzes the performance of devices such as electric cars. In 20ms intervals the following data are stored in internal memory: rms current, rms voltage, power, apparent power, energy, apparent energy, and rpm of a
shaft.
At the end of the measurement, (maximum 11 seconds) data versus time are displayed, can be expanded to view details, or can be stored.
