Table of Content

If the wedges are loose, the stator windings or guide bars can vibrate in the groove, leading to insulation wear and ground fault. In the long run, it will seriously affect the performance and reliability of electrical equipment. Iris Power’s SWA is the solution to this problem. It allows maintenance personnel to easily and efficiently assess the tightness of stator windings in motors or generators. Simultaneously measures, electronically stores and allows for easy, consistent testing of accurate trends in wedge tightness data.

What it means to install a SWA kit to monitor partial discharge (PD) conditions for equipment

According to the traditional method, the stator wedge will be tested for tightness by hammering the wedge and listening to the sound it makes. This approach is often slow and prone to inconsistencies. Therefore, measuring wedge tightness using the SWA electronic method will provide faster, more accurate results, and provide more consistent results.
The Iris Power SWA instrument can be used to test most generator and motor stator slot wedges, including those with ripple springs. The handheld probe will automatically touch each wedge about 30 times in three seconds, the accelerometer collects the data then transmits it to the Iris Power SWA instrument. The final results are presented on the computer as numerical values and color-coded density maps.
Benefits of installing SWA wedge tightness analysis solution:
  • Make well-informed maintenance decisions based on reliable and consistent SWA data.
  • For use with all camcorders, including ribbed spring wedge systems.
  • In standard test mode the tightness of each wedge is compared to predefined values while in advanced mode the tightness of each wedge can be compared to all other wedges in the roll wire, wedge of another coil or any reference selected by the user.
    Numerical, objective, reproducible test data, eliminating the subjectivity of manual methods.
  • Quick and easy wedge tightness testing and analysis, permanent test data record, easy report generation, installation option on robotic vehicle to further automate the inspection process.

Procedure for implementing SWA . wedge tightness analysis solution

Step 1: Stop the machine, take the rotor out of the stator.
Step 2: Use a handheld probe and move along each stator guide.
Step 3: Collect data about the SWA kit and upload it to the software installed on the laptop.
Step 4: From the software, give the graphs and codes about the tightness of the wedges.

Why should you choose to install the Iris Power PD SWA monitoring system provided by S5T?

Why choose Iris Power’s PD SWA monitoring solution?

Overcoming the traditional methods, PD SWA solves the limitations and improves with superior functions. PD SWA measures wedge tightness electronically, giving results faster, more accurately, and providing more consistent results. The Iris Power SWA can even be used to test most generator and motor stator wedges, including those with undulating springs.
