What is a pulse power meter?
The pulse power meter has two functional meanings of pulses in practical applications: one for power counting and the other as a trigger function. Next, we will explain the functions of two different types of impulses.
1. The pulse is used to count the amount of power.
A pulse generator is installed inside the pulse power meter, and a pulse signal is generated when the energy meter detects the consumption or transmission of electricity. This pulse signal can be either electrical or light, depending on the internal design of the energy meter.
When the user consumes power, such as lighting a light bulb or turning on a television, the pulse generator inside the energy meter starts working. It detects the passing current, and when it detects that a current is passing through, a pulse signal is generated. This signal is captured by the meter counter and recorded cumulatively. Each pulse signal generated represents one unit of electrical energy consumed by the user.
The pulse constant of a pulsed energy meter indicates the number of pulses generated by the pulse generator for each kilowatt-hour of electricity consumed. Depending on the model and manufacturing standards, the pulse constant of a pulse power meter can vary. For example, some pulse power meters have a pulse constant of 6400 imp/kWh (meaning that 6400 pulses equal one degree of electricity) or 1200 imp/kWh (meaning that 1200 pulses equal one degree of electricity). In practical applications, when an energy meter receives a pulse signal, it will accumulate and record this signal to achieve the measurement of electricity consumption.
2. The pulse is used as a trigger.
Pulsed energy meters can also enable time-sharing metering. By setting different time constants on the pulse generator, it is possible to measure the consumption of electrical energy over different time periods separately. For instance, different time constants can be set during various periods of the day and night to measure energy consumption during the day and at night.
The pulse power meter also has an anti-tamper feature. Set an anti-tamper switch on the pulse generator of the energy meter. When the energy meter detects that there is stealing electricity in the external circuit, such as disconnecting the voltage or current line of the energy meter, the pulse generator will generate a pulse signal. This signal will be recorded by the anti-tamper counter to realize monitoring and alarm for the tamper behavior.
The process of how a pulse power meter performs a pulse function is based on theory. However, in practical applications, the working principle may vary slightly depending on the design and manufacturing standards. In practical applications, the pulse constant of a pulse power meter is set and adjusted according to actual needs in order to achieve accurate measurement and reasonable control over electric energy usage.
