Motor drive analysers simplify complex troubleshooting

October 05, 2018 // By Nick Flaherty
Fluke has launched two Motor Drive Analysers to simplify troubleshooting on single-phase and three-phase motor-drive systems by providing guided testing that enables technicians to quickly capture the most important measurements.

Motor-drive troubleshooting can be a time-consuming and complicated process with many opportunities for mistakes that can reduce the reliability of the tests. The MDA-510 and MDA-550 eliminate the hassle of setting up complex measurements, simplifying the troubleshooting process and delivering reliable, repeatable test results.

With the MDA-500 Series, technicians simply select a test and the step-by-step guided instructions show precisely where to make voltage and current connections, while the preset measurement profile ensures that all the necessary data is captured for each motor-drive section — from the input to the output, the DC bus, and the motor itself.

The analysers measure key motor-drive parameters including voltage, current, DC bus voltage level and AC ripple, voltage and current unbalance and harmonics (MDA-550 only), voltage modulation, and motor shaft voltage discharges (MDA-550 only). They also perform extended harmonics measurements to identify the effects of low and high order harmonics on electrical power systems.

This allows technicians to conduct guided measurements with graphical step-by-step voltage and current connection diagrams and use simplified measurement setup with preset measurement profiles to automatically trigger data collection based on the chosen test procedure. Additional electrical parameters can be captured with full 500 MHz oscilloscope, meter, and recording capability for complete range of electrical and electronic measurement on industrial systems.

The MDA-500 Series creates as-found and as-left reports quickly and easily with a simple "save to report" at any test point or measurement.
