Oscilloscope Articles: Introduction to Oscilloscopes: The Cathode Ray Oscilloscope is probably the most versatile tool for the development of electronic circuits and systems. The Cathode Ray Oscilloscope allows the amplitude…
Measurement Set Up in Electronic Instrumentation Articles: Microwave Power Measurement Techniques: Microwave Power Measurement Techniques can be done by the use of wavemeters. A wavemeter is an adjustable resonant circuit…
Filters in Electronic Instrumentation Articles: What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus…
Fractional Kilowatt Motors Articles: Single Phase Induction Motor: A Single Phase Induction Motor comprises a single-phase distributed winding on the stator and normal squirrel-cage rotor as shown schematically in Fig.…
High Voltage Test on Radio: Many electrical apparatuses like transformers, line conductors, rotating machines, etc. produce unwanted electrical signals in the radio and high frequency (television band, microwave bands, etc.)…
High Voltage Test on Cables: Cables are very important electrical apparatus for transmission of electrical energy by underground means. They are also very important means for transmitting voltage signals at…
Partial Discharge Measurements: Earlier the testing of insulators and other equipment was based on the insulation resistance measurements, dissipation factor measurements and breakdown tests. It was observed that the dissipation…
Schering Bridge Theory for Three Terminal Measurement: For two terminal measurements the bridge is grounded at its junction points. The supply transformer, detector, and all the components of the bridge…
