Why test motors? Because Motors will eventually fail, typically at the worst possible time causing production to stop.
Not all winding faults start as ground faults. Instead, they can start as a weakness in the winding insulation system that may eventually fault to ground when the motor stops running. Motor testing is integral to the success and efficiency of your business. All-Test Pro instruments ensure that testing your motor is safe, easy, and dependable. Our capabilities for troubleshooting and predictive maintenance are a means of sustaining critical systems and achieving meaningful ROI. Do not leave motor failure up to chance - reap the cost-saving benefits of complete motor testing.
Winding faults
Winding defects begin as energy crossing an insulation fault, which isolates at least one turn. There are 4 basic types of winding faults: Between 2 or more conductors, in a coil Between coils, in the phase Between coils, in different phases Between a coil or phase and ground. Symptoms of winding faults include higher operating temperatures, nuisance tripping, and reduced motor life. The short-term result of these faults is reduced efficiency, and higher operating costs. The long-term result is always motor failure.
Maximize productivity and return on investment
Complete motor maintenance provides you with the tools you need to sustain your most vital business processes, while maximizing productivity. The key to an efficient motor is addressing winding failure, rotor problems, and mechanical faults before they happen. Finding just one of the faults mentioned above can save your organization countless hours of downtime and thousands of dollars in savings, by preventing a drain on productivity and the disruption of necessary processes.
For example, you can perform a simple Test Value Static (TVS™) in just a few minutes. This test establishes an initial reference to a motor-specific parameter value and confirms the health of an induction motor when compared to the reference TVS™. The TVS™ also makes it easy to detect any changes with connections and cables. With ALL-TEST Pro instruments, there is no need for computer software while in the field, so you can get your results instantly and easily.
