A Course In Electrical And Electronic Measurements And Instrumentation

A Course in Electrical and Electronic Measurements and Instrumentation by A.K. Sawhney is a highly-regarded and comprehensive textbook primarily for undergraduate engineering students. The book is widely used in India and other countries for courses in electrical, electronics, and instrumentation engineering.
The book is structured into two main parts. The first part focuses on electrical and electronic measurements, covering the fundamental principles and operational details of various measuring instruments. This includes:
• Electromechanical instruments: Such as ammeters, voltmeters, and wattmeters.
• Measurement of electrical quantities: Methods for measuring resistance, inductance, capacitance, power, and energy.
• Instrument transformers: Potential transformers (PT) and current transformers (CT).
• Bridges and potentiometers: Used for precise measurement of electrical quantities.
The second part delves into electronic instrumentation, with a focus on transducers and modern measurement techniques. Key topics in this section include:
• Transducers: Devices that convert physical quantities into electrical signals.
• Signal conditioning and data acquisition systems: How to process and analyze signals from sensors.
• Display devices and recorders: Including the Cathode Ray Oscilloscope (CRO).
• Measurement of non-electrical quantities: Applying instrumentation to measure things like temperature, pressure, and flow.
The book is known for its clear explanations, extensive coverage of topics, and inclusion of numerous solved and unsolved problems, which makes it a valuable resource for students preparing for university examinations and professional certifications.
