Wattmeter is an instrument for measuring the active power.<\/span> Available in two forms namely analog and digital.<\/span> Active power is obtained by multiplying the apparent power (S) is the multiplication of voltage (V) and current (I) and power factor (Cos \u03b1).<\/span> Therefore wattmeter has two coils, namely the coil turn to detect the voltage value and the static coil to detect the current measured value.<\/span> Construction Wattmeter such as are commonly referred to as a type wattmeter electrodynamic or elektrodinamometer.<\/span><\/p>\n

The principle of the movement of the needle on the principle of rotation of the electric motor.<\/span> Figure 7.3 shows a schematic diagram electrodynamic watt meter.<\/span>

The use of measuring instruments as a measure of electrical power electrodynamic atauwattmeter.Untuk purposes of measurement of electrical power wattmeter then grafting is done as follows:<\/span>

Know the Power Measurement Measure Error with Wattmeter<\/strong><\/span>
\n<\/strong> Electrodynamic Wattmeter has a pair of coils, namely the coil current and coil voltage.<\/span> How connecting the two coils will determine the value of a measuring error is obtained.<\/span> For details, see the way connecting the wattmeter shown in Figure 7.7a \u200b\u200band 7.7.b.<\/span>

In Figure 7.7a, the coil current detecting load current I + Iv, and coil voltage detecting load voltage U. Consequently measured power wattmeter is coupled load power voltage coil power dissipation.<\/span> Therefore, this method is suitable for the measurement of large currents.<\/span><\/p>\n

in the figure 7.7.b, I load coil current and coil voltage detecting load voltage U + Ua.<\/span> As a result, power is measured wattmeter an added load power dissipation coil current.<\/span> Therefore, this method is suitable for the measurement of small currents.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
