The Fluke MDA550 Motor Drive Analyzer, 4 Channel, 500 MHz with Motor Shaft and Harmonics simplifies complex motor-drive troubleshooting with guided test setups and automated drive measurements that provide reliable, repeatable test results on three-phase and single-phase inverter type motor-drive systems. The new Fluke MDA-550 Motor-Drive Analyzers save time and eliminate the hassle of setting up complex measurements, while simplifying the troubleshooting process. Simply select a test and the step-by-step guided measurements show you where to make voltage and current connections, while the preset measurement profiles ensures data capture for each critical motor-drive section-from the input to the output, the DC bus, and the motor itself. The built-in report generator can quickly and easily generate as-found, and as-left reports.
The MDA-550 measures input voltage and current to quickly see whether values are within acceptable limits by comparing the drive's nominal rated voltage to the actual supplied voltage. The system can then check the input current to determine if the current is within the maximum rating and the conductors are suitably sized. This model allows the user to check the voltage unbalance at the input terminals to ensure that the phase unbalance is not too high (> 6-8 %), and that the phase rotation is correct, as well as to check the current unbalance, as excessive unbalance may indicate a drive rectifier problem.
Excessive harmonics are not just a threat to rotating machines but also to other equipment connected to the electrical power system.The MDA-550 visually displays the waveform shape for visual inspection to check whether the harmonic distortion is within an acceptable level and also offers a harmonics spectrum screen which shows both the total harmonic distortion and individual harmonics. This model also has three harmonic ranges, 1st to 51st Harmonics, 1 to 9 kHz and 9 kHz to 150 kHz giving the ability to detect any harmonic pollution problems.
