Transformer

A device that serves as an input source of currents and voltages from an electric power system to instruments, relays, meters, and control devices. The basic design is that of a transformer with the primary winding connected to the power system, and the secondary winding to the sensing and measuring equipment.more....

Alternating current (AC)

Electric current that reverses direction periodically, usually many times per second. Electrical energy is ordinarily generated by a public or a private utility organization and provided to a customer, whether industrial or domestic, as alternating current.more..

Transmission Substation

The three-phase power leaves the generator and enters a transmission substation at the power plant. This substation uses large transformers to convert the generator's voltage (which is at the thousands of volts level) up to extremely high voltages for long-distance transmission on the transmission grid.more....

Power Cable

A power cable is an assembly of two or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed. Flexible power cables are used for portable devices, mobile tools and machinery.more....

The Indonesia Power Grid

Indonesia needs to spend about $27 billion on new plants and power lines by 2012 to meet.....

POWER FACTOR

The majority of electronics designers do not worry about Power Factor (PF); PF is
something that you learnt one day at school in your “electrotechnics course” as being
the cos of j, the phase angle between the voltage and current waveforms.more...

Electric Power Plants

Electric Power Plants have a number of components in common and are an interesting study in the various forms and changes of energy necessary to produce electricity.more...

Safety and Health Topics Electric

Electric power generation, distribution, and transmission hazards are addressed in specific standards for the construction industry. This section highlights OSHA standards, the Regulatory Agenda (a list of actions being taken with regard to OSHA standards), and directives (instructions for compliance officers) and standard interpretations (official letters of interpretation of the standards) related to power transmission and distribution in the construction industry. More....

Electric Generation

Electric Generation
The electricity generation sequence involves taking charge from the Earth, doing work on it to give it energy (expressed in terms of voltage), transporting the energy via a distribution system, using the energy, and dumping the spent charge back to the Earth. The Earth acts as a charge reservoir and reference potential for the energy transfer process. More.....
