electrical measuring device

 Electrical measuring device that is used to measure the electrical quantity  consumed by the electrical device. The electrical measuring devices are as follow:                                                                                           1) VOLT METER                                                                              

                                                                                                    A device that measures the voltage of an electrical circuit or battery or generator is called a volt meter. Electric voltage is usually measured with the help of a volt meter, multi meter or clamp meter. The volt meter is indicated by the letter V. A selector switch is used to measure AC and DC in a volt meter by rotating the switch to the point where V- (Van) or V = (Vac) is written. And D.C. Is measured. The volt meter is connected in parallel to the electrical circuit. Also the value of the resistance of the coil used in the volt meter is higher than that of the ammeter. To check the voltage of single phase, it is measured in the range of 250V. (400 volts) is checked in the range of around 500 V. That is one step above the estimated voltage to the selector switch.

Accuracy is higher if measured in the upper range. H. T. To measure the voltage of the line P.T. (Potential Transformer) / V.T. (Voltage Transformer) / C.V.T. (Capacitive Voltage Transformer) is measured with the help of volt meter.                                                                                                                                                               2) AMMETER                                                                             

                                                                                              An instrument used to measure the current flowing in an electric circuit is called an ammeter or ampere meter. The letter 'A' is indicated on the emitter. Ammeters, clamp meters or multimeters are used to measure current. Since the total current of the ammeter circuit is measured, it is always connected in series and the wire of the coil used in it is thicker than the volt meter which reduces the value of resistivity in it. . C.T. to measure high current. (Current) Transformer) and ammeter are used. The current indicates the load of the circuit or feeder or electrical equipment.                                                                                                                                         3)FREQUENCY METER                                                 

    A frequency meter is used to measure the voltage or frequency of an AC line in an electrical circuit. The unit of frequency is Hertz while the letters H2 or Michael per second (Cycle per second) and frequency. Indicated by letters. It is connected in parallel to the electrical circuit like a volt meter. It is used in power houses and sub-stations. The frequency is calculated using the following formula:


f = PN/ 120 Hz


Where P = no poles in generator

 N-Speed ​​of generator in rpm

 f = Frequency in Hz


The frequency is 50 Hz in Nepal, India, Bhutan and 60 Hz in USA. 50 Hz means AC current or voltage 50 cycles per second. The frequency in DC is zero. In the field of electricity, the frequency is used in the range of Hz, while the frequency used in communications such as telephones and radios is in the range of KHz (kHz), Mega Hz (MHz).                                                                                                                         4) WATT METER                                                            


     A device that measures the power consumed in an electrical circuit It's called a watt meter. Its connection is different from volt meter and ammeter. It consists of two coils such as a current coil and a pressure or voltage coil of which the current coil is connected in series with the load and the pressure coil is connected parallel to the load. This meter is indicated by the letters w or KW or MW. It is used in power houses, sub-stations and large industries. In order to know the demand of the industrial customers of Nepal Electricity Authority and to make the will in KVA, the number shown by the analog demand meter is divided by 0.8. Is converted to KVA and billing of demand is done on the basis of demand. Also in most industries nowadays T.O.D. Since the meter is used, it gives the value of direct demand as KVA. Which makes billing easier.                                                                                                                                                                  5) ENERGY METER                                                          
                                                                                              Energy meter is the types of electrical measuring device that is used to measure the electricity consumed by the electrical appliances.That is, a device connected to a customer's home to measure electricity consumption is called an energy meter. Most energy meters have the letter kWh written on them.

"Nepal Vidyut is connected to the energy meter provided by its main authority to keep a record of electricity consumption in all places where electricity is consumed including home, office, industrial and commercial building. It is connected to load and incoming supply. Parts are current coil, voltage coil, magnet, aluminum disc. , Counter, outer cover, etc. The current supply is connected in series and the voltage / pressure coil is connected to the load coil and parallel.It shows the power consumption in units, where 1 unit is 1 kilowatt load of electricity consumed for 1 hour. The energy meter is also called the kilowatt hour meter.

Information about human heart and malaria

 Heart The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assisting in the removal of metabolic wastes. In humans, the heart is located between the lungs. in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria: and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium. Th...
