Panel Meters are a crucial part in electric power measuring and controlling system, providing extremely accurate readings of the parameters of interest. The DK724 is a type of panel meter designed for power systems, which can detect the magnitude, phase, and frequency of the voltage and current. It is the essential device in many devices, such as voltage measurement, power factor measurement and harmonic analysis.

The typical application of the DK724 is to monitor the power system, including the magnitude, phase, and frequency of the voltage, current, power factor, etc. By obtaining information from both the current and voltage of the system, a user can accurately calculate the system\'s total power consumption, and detect any abnormal status within the system. With the operation of the DK724, users are then able to perform necessary protection, and take corrective measures.

Working Principle of DK724

The DK724 operates by measuring the power supplying to the system by closing the current and voltage loops of the system. The module contains an on-board switching bank, which can close the loops and measure the accurate power factor based on the sinusoidal frequencies of the voltage and current supplied to the system.

Once the circuit is closed, the module begins receiving information from the system. The module is equipped with A/D converters, which are used to convert digital signals into analog signals and transmit the processing results to a remote site. The A/D converter then processes the signals from the system, calculates the parameters of the system, and displays the result on the front panel.

The module also contains a temporary measurement means for measuring instantaneous power. When the instantaneous power exceeds a threshold level, the module will generate a protective relay to protect the system. Furthermore, the module can also monitor harmonic content, calculate system\'s total power consumption and power factor.

To ensure the accuracy of the measured results, the module is equipped with a precision circuit, which can guarantee the metre\'s accuracy and stability. In addition, all parameters will be logged and stored in a data store for future analysis.

Conclusion:

The DK724 is an essential and versatile model for power system measurement and control, providing accurate measurements for voltage, current and power factor along with protection and harmonic analysis. Its precision and high-performance received a lot of appreciations from users, which together with the availability of supporting software, makes it the most preferred model in the market.
