ELECTRICAL ENCYCLOPEDIA

What is an Electricity Meter?   An electricity meter or energy meter is a device that measures the amount of electric energy consumed by a residence, business, or an electrically powered device. Electricity meters are typically calibrated in billing units, the most common one being the kilowatt hour. Periodic readings of electric meters establishes billing cycles and energy used during a cycle.. continue.. How does Electricity Meter Works?   Electric Meter, or Watt-hour Meter, an instrument that measures the amount of electric energy used by a consumer. The meter is calibrated in kilowatt-hours. One kilowatt-hour is the amount of electric energy required to provide 1,000 watts of power for a period of one hour. (Ten 100-watt light bulbs left on for one hour consume one kilowatt-hour of electric energy.). continue.. How to read your Electricity Meter?   The third digit is a three because the digit to the right has not yet passed zero.  If the second dial ...

Circuit Breaker   A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city. continue.. Guidelines for Low Voltage Circuit Breaker   We all want to have a reliable data center, and one key to data center uptime is circuit breaker reliability. As such, a detailed evaluation of the circuit breaker design and functionality at the design stage of the data center is extremely important. This white paper from S...

Electrical Accidents Statistics   Home safety is one of the biggest concerns for consumers today. Not only is the safety of their family a huge issue, but no one wants to lose all of their materials in an accident that could have been prevented. One area that consumers have begun to learn more concerning safety is electricity. Every year, tens of thousands of people are either killed or injured from contact with electricity. Most of these incidents happen because of a lack of safety precautions, as well as overall knowledge in the field of electricity.. continue.. Common causes of electrical accidents   We use electricity every day to light our homes and operate numerous household appliances. We also use electricity in the workplace, of course. Lights and other common household and office appliances are generally safe to use but improper use can lead to serious accidents or even death. Always use electrical appliances as directed. You should take special care when making elec...

LED lamps   An LED lamp (LED light bulb) is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. The LEDs involved may be conventional semiconductor light-emitting diodes, organic LEDs (OLED), or polymer light-emitting diodes (PLED) devices, although PLED technologies are not currently commercially available. Since the light output of individual light-emitting diodes is small compared to incandescent and compact fluorescent lamps, multiple diodes are often used together. In recent years, as diode technology has improved, high power light-emitting diodes with higher lumen output are making it possible to replace other lamps with LED lamps. One high power LED chip used in some commercial LED lights can emit 7,527 lumens while using only 100 watts. LED lamps can be made interchangeable with other types of lamps... continue..     Energy efficient lighting   Manufacturers have expanded the application of LEDs by "clustering" the small bulbs...
