107A High Speed Power Analyzer is a very advanced measurement tool designed to offer the scientist,
engineer, or technician more electrical and mechanical signal information than is normally found in
one single instrument. The Model 107A Power Analyzers are multipurpose instruments designed for
laboratory and field use, for production testing and quality control. High accuracy, wide frequency range,
and high common mode rejection are prerequisites for precision measurements on inverters,
light ballasts and ultrasonic transducers.
The 107A measurement capabilities and simplicity of use are unmatched.
107A High Speed Power Analyzer
| Model | Description |
|---|---|
| 107A-1/0.1 | Single Phase High Speed Power Analyzer, 0.1% accuracy |
| 107A-3/0.3 | Three Phase High Speed Power Analyzer, 0.3% accuracy |
| 107A-3/0.1 | Three Phase High Speed Power Analyzer, 0.1% accuracy |
| 107A-3/0.1M | Three Phase Power Analyzer - dynamic motor testing |
| 107A-3/0.1T | Three Phase Power Analyzer for transformer testing |
Six menu soft keys M1 through M6 and five cursor soft keys control the instrument.
The operating procedure, to configure the display and the interface, to store instrument settings, to set the
scaling factors, to select the operating mode, to select the input, the ranges, and many more features is self
explanatory. You can save your personal instrument settings and have the unit start-up with your personal
configuration at power-on. Efficient data processing permits simultaneous measurements on all three
phases of a three phase system and yields comprehensive signal information including RMS and power
values, harmonics, phase angles, and where applicable mechanical power output, torque, efficiency, and slip.
A programmable data logging function permits to transfer of up to 500 RMS and power values
per
second to a personal computer.
Using the operating software plots of power versus time or speed, or current versus time or
frequency are
easily generated.
The 107A Power Analyzers determines electrical motor torque applied to its load.
No torque transducers are needed. Induction motors and dc motors require a speed transducer,
synchronous motors do not. A special operating mode for dynamic torque measurement in the air gap
of a
generator or motor provides plots of torque versus speed, frequency, or time and helps to
detect undesirable
peaks.
