Electrical Training

Posted on Monday, December 16, 2013 in UEA Blog


On Dec. 11, 2013, UEA Engineers and service and maintenance personnel participated in basic electricity training. The training covered DC circuit, AC circuit, transformers, motor control, control diagrams, and industries proximity sensors, etc. Through this training, the participants gained a good understanding of how to read and interpret electrical diagrams and the proper procedures for troubleshooting electrical circuits. For some participants, it was a refresher of proper electrical skills and tools they may have applied for many years. For others, it was a good opportunity to be exposed to other skills and tools that can provide better and broader understanding about electricity.

The feedback on the training was positive. Everyone involved gained something new from the training class. The instructor explained the concepts in practical ways and illustrated them with concrete examples rather than presenting with complex calculations.

For myself, I have learned some new information and strengthened the understanding of the ladder logic circuitry, particularly, in the following:

1)     Using a digital voltmeter AC to measure a DC battery to determine if the DC battery is “clean” or “Dirty”  (ripple and noise).

2)     The training clarified the confusing distinction on 3-phase AC connections (DELTA connections vs. WYE connections), which I have not previously grasped well from text books and other materials.

3)     A good approach to analyze the electrical control circuits.  First read the control portion and the drive portion. Then look for their interconnections.

Engineers at UEA have an opportunity to work on electrical controls from time to time, even those whose background may not be primarily in electrical engineering. The training classes and continuous education, not only have refreshed our skills, but also increased our confidence and our capability to tackle a multidisciplinary project among mechanical, electrical and hydraulic systems in the product design and development process.
