Definition: The sampling oscilloscope is a special type of digital sampling oscilloscope which is used to examine a very fast signal. In other words, The sampling oscilloscope receives various electrical signal and then togetherly display the signals on the screen. It works on the principle of stroboscopic light in which sample is taken at different portions …
Definition: The generator which is used for generating the linear variable voltage concerning time is known as the time base generator. These waves are used in cathode ray tube for deflecting the beam in a horizontal direction. The time base generator is also used in a radar system for determining the range of the target. The oscilloscope …
Definition: The cathode ray oscilloscope (CRO) is a type of electrical instrument which is used for showing the measurement and analysis of waveforms and others electronic and electrical phenomenon. It is a very fast X-Y plotter shows the input signal versus another signal or versus time. The CROs are used to analyse the waveforms, transient, …
Definition: The measurement error is defined as the difference between the true or actual value and the measured value. The true value is the average of the infinite number of measurements, and the measured value is the precise value. Types of Errors in Measurement The error may arise from the different source and are usually classified …
Definition: An instrument in which zero or null indication determines the magnitude of measured quantity such type of instrument is called a null type instrument. It uses a null detector which indicating the null condition when the measured quantity and the opposite quantity are same. Such type of instrument has high accuracy and also it …
Accuracy Definition: Accuracy is the ability of the instrument to measure the accurate value. In other words, it is the closeness of the measured value to a standard or true value. The accuracy can be obtained by taking the small readings. The small reading reduces the error of the calculation. The accuracy of the system is classified …
Definition: Cable capacitance is defined as the measurement of the electrical charges stored within it. The capacitor in the cable is constructed by two conductive material which is separated by an insulator or dielectric. The capacitance of the cable determines the charging current, charging KVA, and the dielectric loss. The capacitance of a cable transmission line …
Definition: The energy which is caused by the movement of the electrons from one place to another such type of energy is called electrical energy. In other words, electrical energy is the work done by the moving streams of the electrons or charges. Electrical energy is the form of kinetic energy because it produces by …
Definition: Insulation coordination is the process of knowing the insulation levels of the power system components. In other words, it is the process of determining the insulation strength of the equipment. The internal and external insulation of the electrical equipment is exposed to continuous normal voltage and temporary abnormal voltage. The equipment insulation is designed …
Definition: The conductor is the type of metal which allows the electrical current to flow through it. The electrical conductor is generally made up of metals like copper, aluminium and their alloys. In an electrical conductor, the electrical charges moves from atom to atom when the potential difference is applied across them. The electrical conductors are …
