The phase balance test is a simple yet effective method for diagnosing some problems with existing windings and for inspecting new windings before resin treatment. Including thermography enhances diagnostic capabilities, making it a valuable addition to the testing process.

In addition to seal oil, some submersibles have an oil filled stator cavity. The oil in the stator cavity very efficiently transfers heat from the stator winding and core, and especially from the rotor, to the pump casing where convection carries it to the pumpage in which the pump is submerged. While the specifications for seal oil are fairly flexible, stator cavity oil has more constraints.

Have you ever thought about using a step counter on your employees in a test setting? This idea can provide valuable data to help you understand how much movement your workers must perform daily due to the current workshop layout. By analyzing this data, you can identify inefficiencies in the layout that may not be immediately obvious.

This presentation reviews procedures that explain how to identify unmarked leads of three-phase motors with one or two windings.

This article looks at the installation and removal of quick detachable (QD) and taper lock pulleys.

Pumps, compressors, fans and other types of mechanical movement are crucial to our industrial activities. Consequently, the health of these motors directly influences the operational reliability and longevity of the broader industrial ecosystem. Acknowledging this underscores the necessity for performing online health assessments of electric motors.

This presentation focusses on critical close fit tolerances and certain surface finish specifications.

There is one industry that has been quietly recycling since before the start of the previous century. That’s right – over 100 years of recycling. What industry is that? It’s our industry – electrical equipment repair.

The Electrical Apparatus Service Association (EASA) stands as the ultimate team, empowering its members with extraordinary abilities. Through shared best practices, high standards and mutual support, EASA’s international community transforms its members into industry superheroes, ready to tackle any challenge.

When a core loss test reveals localized hot spots, or visual inspection identifies physical damage, the ability to repair the damage in a cost-effective manner means the difference between repair or replacement.
