Three-phase power is a type of power circuit that is characterized by three single-phase AC supplies. Single-phase power supplies one phase at 120 volts, while dual-phase or split-phase power consists of two alternating currents supplied by two wires. Phase systems are alternating current power supplies that are defined by the number of phases in the power supply.

In this article, we’ll specifically discuss three-phase systems and how to diagnose them when problems arise.
Understanding the basics of electric motors can help you understand where the problem may be coming from, while proper diagnostic tools can help you identify and clarify the issue. While electric motors may be complex, diagnosing them doesn’t have to be. But how do you determine how to fix a motor cost-effectively? However, this is not a cost-effective solution - most electric motor problems are entirely fixable with solutions that cost significantly less than a new motor. Some businesses may respond to the problem by simply replacing the motor entirely.
When a motor fails to start, runs hot, continually trips or sputters, there are many possible causes. Electric motors are notoriously difficult to troubleshoot.
