Overload Protection for Electric Motors
Thermal images are an easy way to identify apparent temperature differences in industrial three-phase electrical circuits, compared to their normal operating conditions. By inspecting the thermal differences of all three phases side-by-side, technicians can quickly spot performance anomalies on individual legs due to unbalance or overloading.
Electrical unbalance is generally caused by differing phase loads but may also be due to equipment issues such as high resistance connections. A relatively small unbalance of the voltage...
