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.
A compilation of various power quality information, issues, applications, technologies, news and updates
EMTP-RV: REFERENCE FOR POWER SYSTEM TRANSIENTS
Wednesday, October 26, 2011
EMTP-RV
is a powerful and dedicated software for the simulation and analysis of
transients in power systems. It provides an extensive variety of system
modeling capabilities covering electromagnetic and electromechanical
oscillations ranging in duration from microseconds to seconds. EMTP-RV is the
most comprehensive analysis and simulation program for power system transients.
ISOLATION TRANSFORMERS AGAINST NOISE AND TRANSIENTS
Tuesday, October 18, 2011
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 – ELECTRICAL ENGINEERING MASTER OF THE MONTH
Thursday, October 13, 2011
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
Sunday, October 2, 2011
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.
