As for the surge test, this can help detect any internal shorts in the windings. Hence, to identify the slightest resistance imbalance between the different phases, a winding analysis is ideal. In case internal shorts are occurring within the windings, these issues may not become visible as a ground fault.
In fact, several facilities use a hand-held Megger when checking for insulation strength and ground faults. It is possible to prevent overall motor failure when more is learned about the winding insulation’s dielectric strength.įor an efficient troubleshooting tool, winding analysis is the way to go. Thus, these winding issues can be detected and prevented, along with other relevant problems. These tests give an idea of the remaining lifespan of the equipment as more is found out about its past performance.Īs the motor winding analysis is conducted, it can indicate premature failure and faults of motor components. Limits also help determine when certain actions that prevent equipment failure should be performed. Set a limit if there are obvious changes in order to determine how severe these are. Winding analysis also checks the integrity and condition of the rotor bars. In predictive maintenance there are traditional tests done to know more about a rotor’s insulation. Winding analysis is reliable when it comes to trending both AC and DC rotating equipment. Moreover, this technique can be used when in-place and non-destructive trending of the electrical motors is performed. This is why winding analysis should remain as one of the key components of predictive maintenance operations. For this reason, it helps to perform motor winding analysis to eliminate this concern. Motors can be spared from premature failure and the winding insulation’s dielectric strength can be determined at the same time. Motor windings can be a huge problem with equipment. Business owners can continually find ways to cut costs by maintaining the excellent condition of equipment that will impact the bottom line. Maintenance costs will also be reduced to a minimum as potential issues are detected before they become apparent. This allows motor failures to be minimized and productivity losses avoided. Through winding analysis, critical tests to identify the existing motor winding insulation must be performed.
Through motor current analysis, it is easy to determine when the electric winding insulation malfunctions. These include mechanical and environmental conditions, serious faults and power supply issues. Aside from this, operating conditions that often lead to winding failure on electric motors will be determined. Motor winding analysis serves as the initial step to setting a baseline relevant to the life of electric motors. The information acquired is also more in-depth and sophisticated. It may be performed in addition to motor current analysis, and the electric winding insulation can be classified at the same time.
#How to calculate motor winding data generator
Winding analysis is a non-invasive type of testing motors, as well as generator and transformer windings. Check these areas most and assess and/or avoid potential issues before they occur or get worse. Keep in mind that certain factors can increase the workload or strain on the motor, such as the cycling variation, load and environment.
