What is single phase smart watt hour meter?
What is the measurement of single phase energy using watt-hour meter?
Using a watt-hour meter (i.e., active power meter or energy meter) to measure single-phase power is a widely used power metering method. The watt-hour meter is based on the principle of integrating active power over time and is used to measure the cumulative value of power passing through a circuit over a period of time.
In a single-phase power system, the watt-hour meter records the total power output at a certain point in the system, usually in kilowatt-hours (kWh) as the recording unit. When current passes through the circuit, the watt-hour meter measures the product of the current and voltage (i.e., power) and integrates the power value over time to obtain the total amount of power consumed during the period of time.
This measurement method is not only accurate and reliable, but also can intuitively reflect the consumption of power, which helps users to manage energy and implement energy-saving measures. Therefore, the watt-hour meter has been widely used in power systems and has become one of the important tools in the field of power metering.
How does a single phase electronic energy meter work?
The working principle of a single phase electronic watt hour meter is as follows:
a. Voltage and current measurement:
The single phase watt hour meter first converts the measured voltage (U) and current (I) through the voltage input circuit and the current input circuit for subsequent processing.
b. Power calculation:
1. Use an analog multiplier to multiply the converted voltage (U') and current (I'). The gain of the analog multiplier is K, which generates a signal (U0) proportional to the product of U and I (i.e., active power P).
2. U0 is proportional to active power P, i.e., U0 = K * P.
c. Conversion of analog signal to digital signal:
Next, the analog quantity U0 is converted into a frequency pulse output proportional to the size of UIcosφ (instantaneous value of active power) through a U/f (voltage/frequency) conversion type A/D converter.
d. Electric energy measurement:
The frequency pulses are counted cumulatively by the counter, so as to measure the electric energy value within a certain period of time t. This electric energy value is obtained by integrating the instantaneous value of active power (time accumulation).
e. Display and storage:
The measured electric energy data is stored in the memory inside the electric energy meter and displayed through displays such as digital tubes, which is convenient for users to read and manage.
f. Technical features:
1. The single rate watt hour meter adopts digital circuit technology, microcomputer technology and electronic filtering technology, etc., with the characteristics of high precision, low energy consumption and programmability.
2. It does not require the installation of batteries, and measures electric energy through instantaneous sampling and digital circuit technology to ensure the accuracy and reliability of measurement.
