Diagnostics and repairing of electrical machinery
We offer two systems of diagnostics:
MOTORMONITOR™
A non-invasive condition monitoring and diagnosing system.
Use MOTORMONITOR to easily diagnose these problems:
• cracked or broken rotor bars,
• cracked rotor end rings,
• high resistance joints in squirrel cage windings,
• casting porosities or blow-holes in aluminum die-cast rotors,
• poor joint brazing in fabricated rotors
• rotor winding problems in slip-ring induction motors
• stationary or rotating air gap irregularities
• unbalanced magnetic pull
• mechanical unbalance
• bent shaft, thermal bow
• out-of-round stator, rotor or bearings.
The system allows:
• to diagnose immediately,
• continuous analysis,
• scheduling repair activities,
• analysis after repair,
• storage of tests data and results for trending and further analysis.
Benefits that gives you MOTORMONITOR system:
Save valuable production time:
• testing is performed while your motor is running under normal operation loads,
• the process is non-invasive so production continues running,
• you don't need to tear down for visual inspection.
Improve safety - Remote testing is conducted at the motor switch gear, keeping you away from the motor, with use of clamp tranducers.
Gain valuable information - Your data determines the fault conditions. No historical information is required.
STATORMONITOR™
Analysis of the Condition of Windings Insulation of High-Voltage Machine Stators with Use of Partial Discharge Method
30 - 40 % of high-voltage machines failures - a result of a defect or damage of stator windings.
Non-invasive Monitoring of Stator Insulation Condition
• does not require to stop normal machine's run,
• does not require to use high voltage for analysis,
• does not require to know machine's history,
• does not require traditional off-line examination on halt.
The technique based on 12-year experience.
• the researches are led in Robert Gordon University, Aberdeen sponsored by British Petroleum,
• the test on real objects led by ELECO Electrical Projects, Aberden, ESL Ltd Aberdeen,
• wide use on drilling platforms on the North Sea on electrical machines of particular importance in hazardous environment.
Handy, Easy in Use Diagnostic System allows:
• condition monitoring with unlimited access to tested machines,
• analysis under direct computer control,
• storage of the analysis results,
• scheduling repairs,
• trending of machine insulation life.
