OSHA recommends ways to make your electrical safety program better
Power surges can be very damaging to electronic equipment in various ways, making it important to take precautionary measures in order to avoid them.
Knowing how magnetism and electromagnetic induction work are crucial to understanding how an ac induction motor works and functions.
Motor current analysis provides information on existing issues such as loose connections, burned windings, and grounded windings.
Motor faults and failure can cause disruptions to business operations and lead to loss of productivity and reduced profits.
It is important to verify and improve short-circuit rating to remain in compliance.
Although offline or static testing is an important part of a routine maintenance program, dynamic testing of motors can be done more frequently and, in many cases, with greater benefit.
Proper installation and maintenance of an electrical system’s components help keep the working environment safe while extending the life of the equipment.
The use of VFDs has many benefits including improved process control, energy savings, higher reliability and reduced wear and tear.
The electrical system is sometimes overlook at food processing facilities. Here are three ways to maintain the plant's electrical well-being and prevent potential malfunctions and safety hazards.
The tuned circuit is a fundamental building block among electrical and analog electronic circuits. Understanding how it functions provides insight to power quality, communications, controls, electronic equipment, and many other systems found in industrial manufacturing plants. This article provides a brief tutorial on tuned circuit theory and operation.
Electricity cannot be seen physically; only its effects can be seen or felt. At times, some aspects of electricity can be difficult to understand. One such phenomenon is the presence of different types of power in ac electrical systems. This article presents a physical analogy of electrical power as a refresher to help you understand these concepts further.
The August 14, 2003 blackout emphasized that power quality should not be taken lightly. The blackout was caused by, and affected the power grid — our nation's electrical infrastructure. The issues raised by this event should and will come under scrutiny. Just as the nation looks at its power quality issues, plant engineers must look at power quality issues inside the plant.
A circuit breaker is designed to keep an undesirably large amount of current, voltage, or power out of a given part of an electrical circuit. Industrial circuit breaker categories tend to follow voltage classes, which are divided according to magnitude. The IEEE divides voltage systems into four classes listed in the table titled "IEEE voltage classifications.
