As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

All too often, scientists and engineers tend to take the process of measuring resistance for granted. All it takes is attaching test leads to a digital multimeter (DMM), setting its function to ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Brushless motors have a lot of advantages over traditional brushed motors. However, testing them can be a bit of a pain. Because the resistance of the motor’s coils is usually very low, a standard ...

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...

Understand and comply with relevant codes and standards such as NFPA 70B, NFPA 79, and NEC 110.7 to ensure proper insulation testing procedures. Develop a comprehensive job safety plan that includes ...
