The wattmeter is the device that allows the measurement of the watts that is in a stream of electricity. Watt, also known as watt, is the unit of measurement that is equal to one july per second and that is used to measure the power.
We must be aware that there are fundamentally two types of wattmeters: analog wattmeter and digital wattmeter.
Wattmeters are made up of a moving coil (the voltmeter coil) and two fixed coils (the amperometric coils). The voltmeter coil is connected to the electrical circuit in parallel, while the amperometric coils have a Connection serially.
When the electric current flows through the amperometric coils, a electromagnetic field which has a power proportional to the current. The voltmeter coil, for its part, has a resistance that allows minimizing the current flowing through it. Through a needle located on the voltmeter coil, the wattmeter indicates which is the power of the circuit.
It is important to mention that the overload can damage the wattmeter coils, causing measurements to become inaccurate. According to current, the voltage and the power factor, the superheat will be lower or higher.
Other data that is worth knowing about the aforementioned device that we are dealing with are these:
-The amperometric coil or ammeter, what it does directly is to measure the intensity of the electric current. The unit of measurement that it uses is the ampere and then also other “submeasures” such as the milliamp or even the microampere. It has a parallel resistance that responds to the name of shunt.
– Being able to know the origin of the unexpected rise or fall of a computer is one of the main functions of the aforementioned ammeter, which is also used to repair current surges that are causing the malfunction of a system in question.
-The voltmeter coil is also known as a voltmeter and its mission is to measure the value of the voltage. Volt (V) is used as the main unit of measurement, but other “measurements” can also be used. These include the kilovolt (KV), the micro volt, or the millivoth (mV), for example.
-The frequency range of what is an electronic wattmeter can reach up to 20 megahertz. Of course, to achieve this you have to make use of what are called pentode tubes, which would replace the more “traditional” triodes.
-Currently the wattmeter is very frequently used by professionals who carry out connections to the Wi-Fi network.
It is known as electronic wattmeter, on the other hand, to the instrument that can perform a storage of Energy to sustain a field of electricity. It has conductive plates separated from each other by vacuum or by a dielectric-type material. When placed before a potential difference, the plates of the electronic wattmeter acquire negative and positive electrical charges (depending on the plate), although the changes in the total charge are null.
