LMG500

1 to 8 Channel Power Analyzer

The LMG500 is best-in-class for measurements at:

• Devices, e.g. E-machines, frequency inverters, transformers

• Installations and parts of those power grids and consumers to determine interactions

• Components, e.g. ferrite cores, semiconductors, capacitors

Another application field are CE compliance tests on devices, analyzing the feedback of harmonics and flicker (load variations) and standby power consumption.

The most important features of the LMG500 are:

• Wide dynamic measuring range from 3 V to 1000 V / 3200 Vpeak, 20 mA to 32 A / 120 Apeak in direct measurement only by a single pair of sockets for each voltage and current input.

• Modular with 1 to 8 power measuring channels

• Measuring accuracy at 45 to 65 Hz 0.015 % of reading plus 0.01 % of range

• 3 MSample/s per channel, absolutely gapless sampling with the evaluation of all sampling values

• Capturing transients and fast signal changes by event triggering in parallel to the ongoing measurement

• Group delay between voltage and current measuring input <3 ns as standard to ascertain very precise measurements at low cosj and/or high frequencies

• Harmonics and inter-harmonics up to 50 kHz internally, and up to 1 MHz with an external PC

• Flicker, interactions between network and load

• Ergonomic user interface for easy, intuitive use of the power analyzer

• Real-time evaluation of the measurements in numeric tables and diagrams

101A

Economical solution for many measurement applications

The 101A is suitable for measurements on electronically switched loads. Because of its DC coupling capability correct rms- and power values result at all times. Take the case of line voltage multiplied by half wave rectified current. AC-coupling yields wrong rms current and power, DC-coupling yields correct values.

The 101A is simple to use. In the side menu you select current- and voltage ranges (automatic or manual), synchronization, measurement time, special function “Peak-Hold”, and display modes L1, L2, L3, SUM, and ALL (3-phase display).

In the display number fields you can place any measured quantity from the measurement function selection table including harmonics of current and voltage. In the graphics field waveforms and bar graphs of current and voltage can be displayed.

A load connection box is available which connects your single- or three phase load to the Power Analyzer and to the wall power outlet.

Optional RS-232 interface with Windows Operating Software and battery back up for 6 hours autonomous operation is available. It prevents data loss, such as energy data, during power failure.

107A

HIGH PERFORMANCE EASY TO USE 

The MODEL 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 Infratek 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.
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 Infratek 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.

All is built into the input sections of the Power Analyzer, ready for measurements. It is simple to use, your intuition will guide you to operate the Power Analyzer touch screen correctly. Almost all setting changes are accomplished with two touches on the display screen or two clicks with the wireless mouse.

Four Different measurement functions enhance capabilities 

Standard Measurement 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 internal 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 Measurement 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

Transient Measurement 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”

Power-Speed Measurement 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 end of measurement, (maximum 11 seconds) data versus time
are displayed, can be expanded to view details, or can be stored
