1321TH-S01QFNEVB is a multifunctional high-voltage electricity measurement instrument with extensive applications. It is widely used in the fields of three-phase electricity measurement, harmonic and waveform measurement, leakage current monitoring and storage, so as to maintain the safe and reliable operation of power systems.

1321TH-S01QFEVB voltage meter has good wide-band characteristics and high measurement accuracy, and can quickly and accurately detect current, active power, reactive power, power factor, frequency and all kinds of harmonic waves in the power system. It can also monitor the leakage current of the power system. The instrument can measure the maximum useful load of the voltage system in a short time, and measure and record the sudden load changes and disturbances in the system accurately and quickly.

The main components of 1321TH-S01QFNEVB voltage meter include a low-voltage power supply system, signal sampling system, and digital signal processing system with a memory chip. The main control part is composed of a CPU, a power supply management circuit, a signal preamplification circuit, a signal sampling system, and a cooling system. The signal preamplification circuit is the key part of the detection system and is responsible for the initial transformation of the signal. The signal sampling system converts the high-frequency output signal of the preamplifier into a digital signal through an analog-to-digital converter, and stores it in the memory chip. The CPU processes the digital signal at a high speed, and ultimately displays the measurement results on the LCD screen.

In terms of the working principle of 1321TH-S01QFNEVB voltage meter, the high-voltage power supply system supplies voltage to the meter. The signal sampling system filters, amplifies and recognizes the signal, converts it into a digital signal and sends it to the CPU. The CPU performs digital signal processing and realizes the calculation of various parameters in the electrical system. It then sends the data to the data memory, and the integrated circuit is output to the signal amplifier to drive the LCD display or other external displays. At the same time, the data is sent to the communication interface by serial port communication for communication.

The 1321TH-S01QFNEVB voltage meter is an ideal instrument for measurement and control in the power system. It is widely used in the fields of electricity measurement, harmonic and waveform measurement, leakage current monitoring and storage, and its application range is increasingly expanding. The instrument is of great significance to the development and quality detection of the power industry.
