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…
Rogowski Coil Integrator Design: If a Rogowski Coil Integrator Design is placed surrounding a current carrying conductor, the voltage signal induced in the coil is vi(t) = M dI(t)/dt where…
Peak Reading Voltmeter Circuit: Sometimes it is enough if the Peak Reading Voltmeter Circuit of an impulse voltage wave is measured; its waveshape might already be known or fixed by…
Half and Full Wave Rectifier Circuits: Half and Full Wave Rectifier Circuits for producing high d.c. voltages from a.c. sources may be (a) Half wave, (b) Full wave, or (c) Voltage…
Pure Liquids and Commercial Liquids: Pure liquids are those which are chemically pure and do not contain any other impurity even in traces of 1 in I09, and are structurally…
Oil Circuit Breaker Diagram: In such Oil Circuit Breaker Diagram, some insulating oil (e.g., transformer oil) is used as an arc quenching medium. The contacts are opened under oil and…
Mechanical Principles in Transmission Lines: Mechanical Principles in Transmission Lines design should depend to some extent on the importance of continuity of operation in the line under consideration. In general, the…
Basic Aspects of Control System Design of Microprocessor Based Variable Speed Drives: Based on the examples of drives discussed in the foregoing, general outlines may be drawn for designing the…
