Motor Circuit Analysis

Motors and their inner components are vital for success in a variety of fields. It is common to find crews running machines with electric motors 24/7/365 for maximum production, energy efficiency and workplace safety, so business owners must engage with preventive measures to reduce downtime between projects. ALL-TEST Pro specializes in motor maintenance and troubleshooting, so we bring customers innovative hand-held devices to identify problems directly at the source.

Through easy-to-use controls and connectors, your team can better plan inspections and repair appointments around the equipment you use the most. ALL-TEST Pro wants to see your business succeed, so we enable you to better understand the status of electric motor health and life expectancy with tools for DE energized testing.

DE energized Testing & Motor Circuit Analysis (MCA)™

What is MCA™? Motor Circuit Analysis (MCA™) is a DE energized test method to assess the health of the motor. This method can be initiated from the Motor Control Centre (MCC) or directly at the motor. The advantage to testing from the MCC is that the entire electrical portion of the motor system, including the connections and cables between the test point and the motor, will be evaluated. How Does it Work?

The electrical portion of the three phase motor system is made up of the basic motor circuit, which is nothing more than three simple RCL circuits (resistive, capacitive, inductive). Each basic circuit represents one phase of the three-phase motor system. Since each phase of the motor system is identical, each basic circuit should respond the same way to an applied signal. This is also true for single-phase and DC motors.

ALL-TEST Pro instruments apply a series of low voltage, non-destructive sinusoidal AC signals through the motor windings and measure the response to these signals. Winding faults are indicated by variances in the response to the applied signal through the windings. This DE energized test takes only a few minutes and can even be performed by an entry-level technician.

Why Traditional Megohmmeter Testing Isn’t Enough?

Avoid unplanned downtime by proactively and thoroughly testing your motor for faults. This means going beyond the capabilities of a traditional Megohmmeter. 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.

ALL-TEST Pro offers more complete motor testing than any other options on the market. Our 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 three minutes. Save money and time by proactively detecting developing faults before they cause irreversible motor failures.

DE energized Testing Applications

Companies operating in the industries of wastewater, automotive, steel and power generation benefit from MCA™ testing because the professionals responsible for inspecting your machines are not the ones relying on them for success. Too often, equipment operators won’t seek help until a motor starts to make a grinding sound. Now, you can file maintenance requests appropriately using ALL-TEST Pro products.

Test equipment currently on the floor as well as new pieces coming from manufacturers for long-lasting investments. ALL-TEST Pro sets the standard for motor upkeep, and our DE energized testing devices are ideal in the following areas:
