Difference Between Current Transformer (CT) & Potential Transformer (PT)

The electrical instruments are not directly connected to the meters or control apparatus of high voltage for safety purpose. The instrument transformers like voltage transformer and current transformer are used for connecting the electrical instruments to the measuring instruments.These transformers reduce the voltage and current from high value to the low value which can be …

Static Error

Definition: A static error is defined as the difference between the measured value and the true value of the quantity. The true value is the exact value of the measurement which is impossible to obtain. Hence the approximate true value of the measurement should be taken into consideration. The accuracy is the most important characteristic …

Sampling Oscilloscope

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 …

Time Base Generator

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 …

Cathode Ray Oscilloscope (CRO)

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, …
