Sample rate is 3.2K, and abscissa is sampling number, and vertical coordinate is that (vertical coordinate * 137.5 is relative volt value
True volt value) visible, general line voltage waveform is not complete sine wave, voltage signal due to
Extrinsic factor affects, it may appear that distortion, here it is electric energy pollution problem.
The overtone order of different electrical equipments excitations makes a big difference with harmonic content, this product to
The harmonic wave of electricity equipment motivation carries out specificity analysis, grasps equipment current operating conditions according to harmonic wave attribute,
Judge that equipment is the most properly functioning, whether overburden, failure predication and process can be made in time.To not
Processing targetedly with electrical equipment, specific electrical equipment can be brought assorted by prompting current power information
The harm of degree, understands equipment operation condition in advance, and audiomonitor runs, such as, and general washing machine
It is more sensitive to 7,9,11 subharmonic, when properly functioning, overburden runs and critical fault runs
7,9,11 subharmonic reflected change greatly, can be right by analyzing 7,9,11 subharmonic changes
Washing machine diagnoses.Washing machine typically uses resistance split-phase staring to operate, once in starting circuit
Capacitor and split-phase resistance damage and smash, and motor then cannot run well work, and this is also typically to wash
Clothing machine failure cause, spectrum analysis and washing machine when this product is by using washing machine is normal are critical
Spectrum analysis during fault and then judge that washing machine is properly functioning, overburden runs and critical fault fortune
Market condition, other electrical equipment of a GPRS are properly functioning, overburden runs and the feelings such as critical fault operation
The harmonic characterisitic of condition, the most also can carry out operational diagnostics, ensures that equipment is properly functioning, reduces fault and sends out
Raw, extend electrical equipment service life.
