Fault deterioration prediction diagnosis: Identifying malfunctioning areas of electrical equipment using harmonics!
Diagnosis using harmonics from the 2nd to the 40th! Abnormalities and deterioration in motors, machines, inverters, power transformers, and capacitors can be diagnosed.
Nihon Mekatron Co., Ltd. is engaged in the development of measurement and control systems, and we propose systems that satisfy our customers. Our "Failure Degradation Prediction Diagnosis" is a predictive maintenance system conducted through harmonic diagnosis. After measuring over 30,000 units for more than 10 years and verifying them through disassembly, we found a high correlation between the degradation points and degrees of degradation in equipment components. With harmonic diagnosis (KS-2000), we can diagnose abnormalities and degradation in motors, machinery, inverters, power transformers, and capacitors. [Measurement Items (Excerpt)] ■ Motor Section ● Rotating shaft, bearings, installation ● Insulation and vibration of windings ● Damage to bearings and housing ● Uniform air gap ■ Load Section ● Bearing damage, foreign object attachment ● Coupling abnormalities, shaft balance ● Abnormalities in rotating shaft, valve wear ● Damage to gears and belts ■ Inverter ● Smoothing capacitors ● Control boards ● Power elements ● Drive boards *For more details, please refer to the PDF document or feel free to contact us.

basic information
**Features** - Non-contact live line diagnosis Investigations can be conducted without stopping the equipment. It is also possible to investigate degradation symptoms (such as overheating, discharge phenomena, leakage current, etc.) that can only be measured in a live line state. - Diagnosis of mechanical and electrical systems This diagnostic device uses sensing technology to understand the condition of equipment and analytical technology to predict abnormalities, analyzing and diagnosing current and the "harmonics" within it in detail, quantifying and evaluating the results. - Diagnostic result report The obtained harmonic components are used to comprehensively assess the diagnostic results for four locations in the motor section, four locations in the load section, and four locations in the inverter section, along with the imbalance rates classified as A, B1, B2, B3, and C. - Fault degradation prediction and forecast curve By conducting regular diagnostics, it enables the creation of a fault prediction degradation forecast curve, contributing to the extension of the lifespan of equipment. **Verification Results Case** <Diagnostic Results> Winding insulation C, current diagnosis B2, indicating a trend of initial insulation degradation in the winding. <Dismantling Verification> Due to overheating, the varnish was thin, and it was in a state just before a rare short circuit.
