#MotorTalkMonday – single-phasing
Did you know that single-phasing is responsible for up to 14% of motor failures? This occurs when one phase of a three-phase motor loses power, causing the other phases to work harder and potentially overheat. If not recognized and addressed quickly, this can lead to overheating, reduced power output, or even motor failure.
So what causes this failure? Common causes include a blown fuse or tripped protective device, an open contactor, broken power lines, or bad connections. To prevent single-phasing, you can employ a phase failure or loss of phase relay, implement individual overload protection, utilize monitoring relays, or consider manual motor protectors.
It is important to monitor your motor for potential signs of single-phasing so you can deal with the problem as quickly and efficiently as possible. One of the easiest ways to monitor your motors is with ABB Ability™ Smart Sensors. The Smart Sensor can pick up on changes in temperature or vibration, which can be caused by single-phasing. Smart Sensors can help you catch issues before it turns into a major problem!
