Measuring efficiency with high precision: simultaneous measurement of input and output

Preventative maintenance is crucial to maintaining reliable plant operations and reducing costly downtime. As electrical cables are found everywhere in industrial plants, insulaiton testing is one of the many active measures used in this type of periodic equipment validation. Insulation testers ensure the integrity of electrical cables by measuring the quality of the conductivity state. By diagnosing insulation quality early on, you can prevent harmful leakage currents from destroying nearby equipment or harming your personnel.

If a product uses power, then power consumption and power quality measurements must be made as part of product design and test. These measurements are essential to optimize product design, comply with standards and provide nameplate information to customers.
This article will discuss best practices for making these measurements, starting with power measurement basics and proceeding to the types of instruments and associated components typically used to make measurements. The article will conclude with real-world examples, which apply the information imparted earlier in the article to solve practical measurement problems. Although most of us have been exposed to basic power measurement equations, a primer is helpful to summarize this information and to show how it applies to product design and test.

There are several factors for a user to consider when using an IEPE accelerometer, particularly when used with newly available integrated signal conditioner/data acquisition systems. Correctly managing these factors will help the user avoid erroneous data from their IEPE accelerometer and ensure the quality of the measurement data is at the level they expect and require.

One of the main responsibilities of engineers and technicians is data analysis, and this article will show how multi-touch technologies can be used to improve the performance of this and other related tasks.

With the increased demand in electric-hybrid vehicles, the electromechanical designs of in-vehicle systems are becoming more sophisticated and there has been a demand shift towards high efficiency brushless direct current motor (BLDC) implementation. Think of motorized seat adjustment, electric window, power steering, HVAC fans, pumps, etc. In many of these systems various types of motors are used as actuators; more specifically, 3-phase BLDC motors are gaining popularity as they provide these important advantages:

• Improved speed vs torque characteristics
• High dynamic response
• High efficiency
• Extended speed ranges
• Long operation life
