The phase instrument is the abbreviation of the "phase analyzer".It also refers to the "phase instrument" (common name) in the physical form.Here are only "phase analyzers" that exist on software.The phase instrument is a new generation of instrumental metering and relay protection major for electric power systems and relay protection.It is also widely suitable for electrical equipment manufacturing, petrochemical, steel metallurgy, railway electrification, scientific research and teaching and other departments.
The role of the phase instrument
First, when the waveform of the dual -channel (stereo) music is detected, we assume that the left sound waveform emits a tone of 6246, and the right sound waveform emits 1234 tones.Or when the two channels (referring to the left channel, right channel) have different parameters such as level, tone, and sound, the phase analyzer can use a certain amount of samples to analyze and use icons to indicate.At this time, the icon of the phase analyzer is like a messy line.For example, "Dragon Boxing" in popular music, in a certain period of time, we can hear that there are people talking in the left and right channels, and the channels on both sides of the sound are issued in turn.Second, the phase analyzer can detect the vocal direction of two sound sources (referring to the left channel, right channel).Just as the human ears are judged by the noise clump of the car engine, the left ear faded out -when the right ear fades in, you can know: the left side of the car is driving to the right.The same is true of the phase analyzer, but it changes the abstract things and expresses it with images.Third, the single -sound waveform, the icon of the phase analyzer is similar to the level.If we convert a monocular waveform into a three -dimensional sound, because the phase analyzer icon is still similar to the level, we can assert that there is no difference in parameters such as the level, tone, and tone on both sides of the waveforms.It may be possible to copy a monocular waveform into a three -dimensional sound waveform as a monocular cloning phase analyzer. You can use this process to detect whether the three -dimensional sound of the music is cloned (fake) or the original (real).
Phaseer price
The price of the phase instrument is around 4200 yuan.The phase instrument set three -phase voltage, current, phase, phase, phase, frequency, power power, powerless power, power factor, etc. in one body;Frequent electrical parameters.The phase instrument has a variety of display methods such as vector charts, tables, and sub -channels. The table method can display more than 20 parameters when displayed. The measurement data is clear at a glance. The color vector map can be exquisite and clear.A variety of information such as angle, the vector diagram can be set to clockwise or counterclockwise as a positive direction, the direction of the 12 oclock or three oclock is 0 degrees angle direction, and the benchmark angle is 330 ° or 0 °, which is in line with various user habits.And wiring.
How to use the phase instrument
1. Press the ON-OFF button to correct the test parameters and quantity of the rotation function switch.2. Measure the AC voltage, dial the rotation switch to the 500V quantity corresponding to the parameter U1, and the measured voltage will be from the U1 jack.Input can be measured.If the measurement value is less than 200V, it can be rotated directly to the 200V limit measurement of the corresponding 200V to improve the measurement accuracy.3. Measure the AC current, dial the rotating switch to the 10A limit corresponding to the parameter i1, and insert the wire plug into the i1 jack with the current transformer.Can be measured.Similarly, if the measurement value is less than 2A, the 2A limit measurement can be directly rotated to the corresponding 2A limit of i1 to improve the measurement accuracy.When measuring current, the rotating switch can also be dial to the corresponding limit of the parameter i2, and the measurement clamp with the labeled 2#can be connected to the i2 jack.4. Measure the phase angle between the two voltages, and the phase angle of the U2 lags behind U2 is measured, and the switch is allocated to the parameter U1U2.During the measurement process, you can rotate the switch clockwise at any time until the limit of the parameter U1, measure the U1 input voltage, or rotate the switch on the counter to each amount of the parameter U2, and measure the U2 input voltage.
