Working principle and application of single-phase AC voltage transmitter

Single-phase AC voltage transmitter, a device specially used to measure and convert single-phase AC voltage signals, uses non-contact inductive coupling technology or potentiometer adjustment technology to achieve accurate voltage measurement and signal conversion. It can convert the measured voltage signal into standardized DC voltage, current or other output signal forms to meet the needs of various application scenarios.

Before we understand the single-phase AC voltage transmitter in depth, we need to first understand the characteristics of single-phase AC voltage. Single-phase AC voltage refers to an AC signal with only one phase. Its waveform is usually sinusoidal and the frequency is generally 50Hz or 60Hz. Single-phase AC voltage is widely used in household electricity, industrial automation, and energy management.

The working principle of a single-phase AC voltage transmitter is relatively complex, mainly involving signal input, signal processing and output.

The first is the signal input part. The single-phase AC voltage transmitter uses non-contact inductive coupling technology or potentiometer adjustment technology to receive the measured voltage signal. When the measured voltage signal is input to the transmitter, it will pass through the circuit in the signal input part, resulting in corresponding inductive coupling or potentiometer adjustment effect.

Then there is the signal processing part, which performs multiple processes on the input voltage signal, including amplification, filtering, linearization and isolation. These processing measures can improve the stability, accuracy and reliability of the signal. In addition, other special processing can be performed according to specific needs, such as temperature compensation, phase correction, etc.

Finally, there is the output part. After signal processing, the single-phase AC voltage transmitter outputs the converted signal in the form of standardized DC voltage, current or other signals. These output signals can be connected to other devices or systems for a variety of functions including monitoring, control and measurement.

Single-phase AC voltage transmitters play an important role in many areas, including industrial automation, energy management, and home power. In industrial automation, it can be used to monitor the voltage conditions of electrical equipment and power grids to ensure normal operation and protection of equipment. At the same time, the voltage signal is converted into a standardized output signal for processing and feedback control by other control systems. In energy management, single-phase AC voltage transmitters can be used to measure and monitor the voltage quality and stability of the power grid, and detect voltage abnormalities in a timely manner to avoid power failures and losses. In addition, it can also perform energy consumption analysis and optimization to improve energy efficiency. In the field of household electricity, single-phase AC voltage transmitters are used in household power monitoring systems to help household users understand voltage conditions in real time, monitor and manage power consumption, rationally adjust power consumption behavior, and reduce energy consumption and expenses.

In general, single-phase AC voltage transmitters play a vital role in different application scenarios. They achieve efficient and accurate voltage measurement and signal transmission by converting voltage signals into standard signals suitable for processing. Provides strong support for electrical monitoring and control in various fields.
