ELECTRIC METERS FOR POWER AND ENERGY READING

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..



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..


The third digit is a three because the digit to the right has not yet passed zero.  If the second dial from the right was between the zero and the one, then the third digit would have been a four.  Easy isn't it!  To practice, go outside to your home or business and record the readings for several days in a row.    By subtracting yesterday's reading from today's reading, you can get a feel for how much energy (kilowatt hours) you use each day..continue..

An electric meter is a device that measures and registers the integral of an electrical quantity with respect to time. The term “meter” is also used in a general sense to designate any type of measuring device including all types of electrical measuring instruments. Use of “meter” as a suffix to a compound word (e.g., voltmeter, ammeter, frequency meter) is universally accepted. However, in this chapter the narrow meaning of “electric meter” is used..continue..


Defective Meters
Although electric meters are hardy devices, it is always possible that some of them may develop defects over extended service periods. To ensure that meters on the system will remain accurate, the distributor should implement a periodic meter testing program. Periodic meter testing is required by TVA although testing intervals are not specified. A program meeting current industry standards should be designed so each meter on the system is tested no less frequently than shown in table.continue..

POWER SYSTEMS LOSS.COM: LOSSES IN ELECTRICAL SYSTEM

What is powersystemsloss all about?    System's loss reduction is now one of the most growing trends in every electric distribution utility. Primarily triggered by economics and regulation concerns, Transmission and Distribution companies now sets more focus in reducing losses and become as an efficient utility as possible in delivering power. Information found in this site will be very useful not only to electrical practitioners but it is also our goal to help students better understand the actual world. Thank you and lets all enjoy learning! continue..   Back to basic    n case you don't know, the power we get from our household electrical outlet didn't just appear in the thin air. It may appear that it is coming out from our walls but we all know that looks can be deceiving. Before reaching our respective homes, electric current passes through miles and miles of c...

FRUITS AS BATTERY AND SOURCE OF ELECTRICITY

Electric Fruits Project   The purpose of this project was to find out which fruit would generate enough electricity to light a light bulb and to discover which fruit would light the bulb the longest. To conduct my experiments I used a Multimeter, copper and zinc wires & electrodes, alligator clips with leads, various light bulbs and five types of fruits. continue.. Why Do Citrus Fruits Produce Electricity?   In order to generate electricity, there must be a power source and a complete circuit. When using a citrus fruit to create electricity, these rules still apply. In a simple experiment using a citrus fruit, the components of the circuit include: a lemon or other fruit, wire, two different metal elements and a small light bulb. The lemon in this circuit serves as the battery and power source. continue.. Fruit Power Project   Purpose To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or li...

ELECTROCUTION: ELECTRIC ACCIDENT THAT CAN BE AVOIDIED

Electrocution   Electrocution is a type of electric shock that, as determined by a stopped heart, can end life. Electrocution is frequently used to refer to any electric shock received but is technically incorrect; the choice of definition varies from dictionary to dictionary. However, in the vernacular, the term electrocution is used to mean: death, murder or a sudden accident caused by an electric shock. deliberate execution by means of an electric shock, such as an electric chair; the word "electrocution" is a portmanteau for "electrical execution".. continue.. Electric Shock   Electric Shock of a (human) body with any source of electricity that causes a sufficient current through the skin, muscles or hair. Typically, the expression is used to denote an unwanted exposure to electricity, hence the effects are considered undesirable. The minimum current a human can feel depends on the current type (AC or DC) and frequency. A person can feel at least 1 mA (rm...
