Flow Measurement (Mechanical Transducers): The measurement of flow rate and quantity is the oldest of all measurements of process variables in the field of instrumentation. It is used to determine…
Measurement of Physical Quantities: Measurement of Physical Quantities is given by Displacement Measurement Strain Measurement Force Measurement Torque Measurement Pressure Measurement Temperature Measurement Water-Level Indicator Measurement and Display of Speed…
Measurement of Electrical Quantities: Measurement of electrical quantities which includes Measurement of Voltage Measurement of Current Frequency Measurement Phase-Angle Measurement Power-Factor Measurement Impedance Measurement VA Measurement Power Measurement VAR Measurement…
Power Measurement in Single Phase Circuit by Wattmeter: Wattmeters are generally used to measure power in the circuits. A wattmeter principally consists of two coils, one coil is called the…
Measurement of High Voltage and Currents Articles: Series Resistance Microammeter: High d.c. voltages are usually measured by connecting a very high resistance (few hundreds of megaohms) in Series Resistance Microammeter…
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…
Measurement of High Direct Current: High magnitude direct currents are measured using a resistive shunt of low ohmic value. The voltage drop across the resistance is measured with a millivoltmeter.…
Standing Wave Ratio Measurements: Standing wave are created along the length of a transmission line due to the mismatch between the characteristic impedance Z0 and the terminating impedance of the…
