What are Electrical Measuring Instruments?
They are tools used to measure various electrical values such as current, voltage, resistance, capacitance, and more.
These devices assist technicians and engineers in testing and analyzing electrical systems to ensure their safe and efficient operation.
They are also used to detect faults and adjust the performance of electrical equipment according to their type.
Classification of Electrical Measuring Instruments
Electrical measuring instruments are classified into two main types: Analog measuring instruments and Digital measuring instruments. Here is a brief explanation of each:
Analog Instruments: Depend on a moving needle indicator to display the measured value. They are simple and allow easy reading of continuous changes.
Digital Instruments: Display electrical values on a digital screen, providing higher accuracy and easier reading. They often include additional features such as data storage and connectivity to other devices.
Types of Electrical Measuring Instruments
Electrical measuring instruments cover a wide range of devices used to measure different electrical properties accurately and effectively. Below are the main types and their uses:
Ammeter: Measures the electric current flowing in a circuit.
Voltmeter: Measures the voltage difference between two points in a circuit.
Ohmmeter: Measures the electrical resistance of components.
Multimeter: A multifunction measuring device that combines current, voltage, and resistance measurements in one tool.
Clamp Meter: A type of electrical measuring device used specifically to measure current in wires without needing to disconnect the circuit.
