Fundamentals of Electrical Engineering I
By:
Don Johnson, From its beginnings in the late nineteenth century, electrical engineering has blossomed from focusing on
electrical circuits for power, telegraphy and telephony to focusing on a much broader range of disciplines.
However, the underlying themes are relevant today: Power creation and transmission and information have
been the underlying themes of electrical engineering for a century and a half. This course concentrates on
the latter theme: the representation, manipulation, transmission, and reception of information by electrical
means. This course describes what information is, how engineers quantify information, and how electrical
signals represent information.

timesAC UPS SYSTEM SOLUTION FOR AN INDUSTRIAL
A UPS system is a vital part in a complex power conversion
and distribution scheme for process control and monitoring.
Evaluating the best suitable configuration for the given
requirements and topologies is a key issue during the
engineering stage for a new application or for refurbishment of
an existing set-up. However, the decisive / determining factors
are multifaceted and linked together. In any case there is no
“one and only” solution. Closer investigations often reveal that
simple and cost effective configurations fulfil the specifications
much better than the complicated “high-end” choice. The UPS
technology elaborated in this paper is based on double
conversion concept with thyristorised rectifiers and pulse width
modulated inverters, which is a state of the art UPS solution for
heavy industrial applications.

timesElectrical Systems and Safety Oversight Training
KNOWLEDGE OF ELECTRICAL THEORY & EQUIPMENT
The purpose of this reference guide is to provide a document that contains the information required for a Department of Energy (DOE)/National Nuclear Security Administration (NNSA) technical employee to successfully complete the Electrical Systems and Safety Oversight Functional Area Qualification Standard (FAQS). Information essential to meeting the qualification requirements is provided; however, some competency statements require extensive knowledge or skill development. Reproducing all the required information for those statements in this document is not practical. In those instances, the candidate is directed to additional resources.

timesSingle Phase Transformers
Using the transformer model and referred loads, compute the voltages and currents that
correspond to each of the three load tests. Use the primary voltage from the load tests and
compute the primary current and power as well as the secondary voltage, current, and power.
Compare these values to the measured values in a table along with percent errors.
