Is it sufficient for the equipment maintenance person to only conduct self-inspections? Non-contact harmonic diagnosis.
Diagnosis of harmonics from the 2nd to the 40th! Diagnosing abnormalities and deterioration in motors, machinery, inverters, power transformers, and capacitors! Case studies available!
"Failure Degradation Prediction Diagnosis" is a predictive maintenance system conducted through harmonic diagnosis. By using harmonic diagnosis (KS-2000), abnormalities and degradation in motors, machinery, inverters, power transformers, and capacitors can be diagnosed. This document introduces a case study of harmonic diagnosis at M Corporation's Niigata factory. It includes the motivation for introducing harmonic diagnosis technology, equipment specifications, current measurement values, and more. Additionally, as part of the disassembly verification, the diagnostic results for the motor winding section and rotor/stator sections are also presented. Images of the compressor burn damage are also included. We encourage you to read it.

basic information
**Features** - Non-contact live line diagnosis Investigations can be conducted without stopping equipment. It is also possible to investigate degradation symptoms (overheating, discharge phenomena, leakage current, etc.) that can only be measured in a live 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 acquired harmonic components are comprehensively assessed along with the diagnosis results for four locations in the motor section, four locations in the load section, and four locations in the inverter section, providing A, B1, B2, B3, and C judgment imbalance rates. - 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 tendency for initial insulation degradation of the winding. <Disassembly Verification> Due to overheating, the varnish was thin, and it was in a state just before a rare short circuit. *For more details, please refer to the PDF document or feel free to contact us.*
