Cable ground, cable neutral, cable phase

Cable  ground,  cable neutral,  cable phase

The electrical system that goes to our homes, if the use of electric system 1 phase, usually made up of three cables:

The first is the phase cable (red) which is a power source back and forth (positive and negative phase phase back and forth continuously). This cable is a cable that carries power from the hydroelectric (PLN for example); These cables are usually called hot wires (hot), to be compared as the positive Pole on the direct current electrical system (although in physics is not right).

Second is the (black) cable neutral. This cable is basically zero voltage reference cables, connected to the soil in power plants, on specific points (on electric pole) electric network cabling is connected to neutral to ground voltage on the transformer down primarily from high-voltage channels three lines into three phases plus line line ground (four lines) that will be distributed in houses or other.

To address the leakage electric current of the equipment each home installed cable ground (black) connected by a metal plug ground to put together with the neutral cable channels of electric nets mounted on a distance closest to the electric meter or tool close to switch.

In the events of Hurricane Electric space (space electrical storm) are great, there is likely a current will flow from the underlying soil to reference other land that far. This natural phenomenon can trigger large-scale lamp dead events.

Third is the ground or Ground wires (blue, green, black and red colors aside). This cable is a zero reference in the location of the user, which is connected to ground (ground) at the home user, these cables really come from the metal that was planted in the ground in our homes, cable is a cable that is connected to the security body (chassis) alat2 electricity at home to ensure that users of such equipment would not be subjected to electric shocks.

The third cable was rarely fitted to dirumah-rumah inhabitants, be sure the technician (instalatir) electric cord you attach the ground (ground) on the electrical system at home. This is important, because the installer is an absolute requirement for your safety from the hazards of electrical shock that could be fatal and also several power tools that are sensitive will not work properly if there are electrical induction that appears on chassisnya (for example, due to the effects of current Eddy).

alternating current

alternating current benefit

The flow of electricity flows from positive to negative channels channels. With a direct current of electricity if we hold only the positive cable (but not holding the negative cable), power will not flow into our bodies (we are not exposed to strum Tuesday). Similarly if we just hold a negative line.

With electricity alternating current, electricity can also flow into the Earth (or the floor). This is caused by an electricity system using the Earth as a reference voltage neutral (ground). This reference, which is usually in pairs in two places (one on the ground in an electric pole and another one on the ground at home). Therefore, if we hold the power source and our feet are treading the Earth or our hands touching the wall, the voltage difference between the electrical cable in hand with tension in the legs (ground), making the electricity flowing from hand to foot so we will experience electric shocks ("exposed strum Tuesday").

Electrical power can be stored, for example on a battery or batteries. Small, for example electricity stored in batteries, won't stun effect on the body. The car battery is great, there is usually a slight stun effect, although not too large and dangerous. Electricity flows from the positive pole of the battery/batteries into the negative pole.

Electrical properties

Electrical properties

Electricity gave rise to the 4 fundamental forces of nature, and its remains in objects can be measured. In this case, the phrase "the amount of electricity used also with the phrase" electrical charge "as well as" the amount of the charge ". There are 2 types of electric charge: positive and negative. Through experiments, payload-a kind of mutual refused and charge-opposite sex attracted to each other. The magnitude of this style is exciting and rejecting established by Coulomb. Some of the effects of power discussed in electrical and electromagnetic phenomena.

The SI unit of electric charge is the coulomb, which has stood for "C". The symbol Q is used in the equation to represent a quantity of electricity or charge. For example, "Q = 0.5 C" means "the quantity of electric charge is the coulomb 0.5".

If the electricity flowing through the special materials, such as tungsten and tungsten, of light emitted by metal will flare it up. Such materials are used in a light bulb (bulb or bulblamp).

Whenever electricity flows through materials which have barriers, it will be hot removed. The greater the flow of electricity, then the heat arising will be doubled. These properties are used on elements of irons and electric stove.

What is Electricity

The definition of Electricity

Electricity is the nature of objects that arise from the presence of electric charge. Electricity, can also be interpreted as follows:

Electricity is the condition of certain subatomic particles, such as electrons and protons, which led to the withdrawal and rejection of styles in between.

Electricity is a source of energy that is transmitted via cable. Electric current arises because the electric charge flows from positive to negative channels channels.

Along with magnetism, electricity form the fundamental interaction is known as electromagnetism. Electricity allows the occurrence of many physical phenomena which are widely known, such as lightning, electric field and electric current. Electricity is widely used in industrial applications such as electronic and electrical power.

Thermal energy storage

Thermal energy storage

Thermal energy storage is temporary energy storage or removal of heat for use at a later date. Thermal energy storage that are common at this time is useful for ice storage move heat when needed. Ice is made at night when peak loads. This method is recommended and developed by the u.s. Green Building Council's Leadership in Energy Efficiency program and Environmental Design to arouse the development of building design-capable high that is safe for the environment.

The advantage of making ice at night include: after passing the peak load electricity have lower fees so that cheaper, and energy to cool the ice on a cold night is faster and requires less energy, so the ice can be produced in an amount more. It can be said that in this way, a lot of energy from the power plant was saved while more energy is released from storage for some time.
