TB240116S48 Single-Phase Wattmeter Didactic Equipment Electrical Engineering Lab Equipment
I.Product Overview
1.1 Overview
A single-phase wattmeter is an instrument used to measure the electrical power in a single-phase circuit. It is based on the principle of electromagnetic induction. Through the interaction between the current coil and the voltage coil, the pointer deflects to indicate the power. It is widely used in power systems, laboratories and various electrical equipment for power measurement.
1.2 Features
High measurement accuracy: It can accurately measure the active power in a single-phase circuit, providing reliable data support for the operation of the power system and the energy consumption analysis of the equipment.
Intuitive reading: The pointer display is intuitive and easy to read, making it easy to quickly read the measured value on site.
Strong applicability: It is not only suitable for AC circuits, but also can be used for power measurement of DC circuits.
II.Working Principle
The single-phase power meter uses the principle of electromagnetic induction to measure the power of a circuit. Its current coil is connected in series with the circuit being measured, and the current is proportional to the current of the circuit being measured; the voltage coil is connected in parallel with the circuit being measured, and the current is proportional to the voltage of the circuit being measured. When the magnetic field generated by the current coil and the voltage coil interacts, the pointer will deflect, and the deflection angle of the pointer is proportional to the power of the circuit being measured, thereby indicating the power.
