Motor-Generator (M-G) set is basically a combination of a motor and generator, although it is physically different from an ordinary electric motor that is attached to a separate generator. It has many practical functions that generally involve converting voltage, frequency and phase of power. However, this post will focus on its power quality applications, as it is a mature technology used for isolating sensitive and critical loads from voltage sags and interruptions. Also, it is available in various sizes and configurations to suit different purposes.

Isolation Transformer is a special type of transformer, wherein the primary and secondary windings are physically separated through a so-called double insulation. Also, an isolation transformer with electrostatic shields is commonly employed as power supplies for sensitive devices like computers, laboratory measurement instruments and medical equipment.

Joseph Henry (1797-1878) was born near Albany, New York. His ambition was to become an actor until by chance at the age of 16 he happened to read a book of science, which caused him to devote his life to the acquisition of knowledge. That event turns out to be the beginning of Henry’s rise as the leading American scientist after Benjamin Franklin and until Willard Gibbs.

ESD or Antistatic Wrist Strap is a protective device worn by personnel while working on sensitive electronic components in order to safely direct static electricity from their body to ground, and avoid equipment damage. This is because the antistatic wrist strap can avert the accumulation of static electricity, which can eventually lead to an electrostatic discharge.
- I am a Professional Electrical Engineer with a Masters Degree in Business Administration. My interest is in Power Quality, Diagnostic Testing and Protective Relaying. I have been working in an electric distribution utility for more than a decade. I handle PQ studies, power system analysis, diagnostic testing, protective relaying and capital budgeting for company projects.
