Current transformer and Potential transformer: These Current transformer and Potential transformer are designed to meet the specific need of measurement and instrumentation systems, which accept voltages in the range of 0-120 V and currents upto…
Parallel RLC Circuit Resonance: Parallel RLC Circuit Resonance - Basically, parallel resonance occurs when XCÂ = XL. The frequency at which resonance occurs is called the resonant frequency. When XC = XL, the two branch currents…
What is a Temperature Transducer?: Temperature Transducer is one of the most widely measured and controlled variable in industry, as a lot of products during manufacturing requires controlled temperature at various stages of processing. A…
Economic Operation of Power Plants Interview Questions and Answers: 1. Is the cost of fuel directly proportional to power output ? Ans. No, the cost of fuel does not vary directly in proportion to the…
Current to Voltage Converter Circuit: A device that produces a voltage proportional to input signal current is called a Current to Voltage Converter Circuit. The circuit arrangement is shown in Fig. 36.27. In this circuit,…
RX Meter Circuit in Measuring Instruments: An RX Meter Circuit in Measuring Instruments is used to measure the separate resistive and reactive components of a parallel Z network. It is especially useful in the design…
Cryogenically Cooled Amplifiers: The term solid-state is used deliberately here; it does not mean "semiconductor." In terms of the somewhat older maser parlance, it means the opposite of gaseous, i.e., ruby. The cross section of…
Transformer Protection Types: Nature of Transformer Faults: Power transformers, being static, totally enclosed and oil immersed develop faults only rarely but the consequences of even a rare fault may be serious, unless the transformer is…
Capacitance of Three Phase Transmission Line with Equilateral Spacing: Figure 3.5 shows a Capacitance of Three Phase Transmission Line with Equilateral Spacing composed of three identical conductors of radius r placed in equilateral configuration. Using…
Equivalent Circuit of Practical Op Amp: The Circuit which represents op-amp parameters in terms of physical components, for the analysis purpose is called equivalent circuit of an op-amp. The Equivalent Circuit of Practical Op Amp…
