Megohmmeter insulation testing will only detect faults to ground. Since only a portion of motor electrical winding failures begin as ground faults, they will go undetected using this method alone. Moreover, surge testing requires the application of high voltages. This can be destructive when testing a motor, making it an unsuitable method for troubleshooting and true predictive maintenance testing.
Megohmmeter insulation testing will only detect faults to ground. Since only a portion of motor electrical winding All-Test Pro products offer more complete motor testing than any other options on the market. These instruments go above and beyond normal testing equipment for accurate, safe, and fast motor testing. Motor testing using an MCA™ tool is very easy to implement, and the test takes less than 3 minutes. Save money and time by proactively detecting developing faults before they cause irreversible motor failures.
