Power facility monitoring business
We seek to establish an environment which will keep nature and our customers fulfilled.
Prevention, diagnosis system for Power facility
Power facility diagnosis is crucial for stable power supply. For this, preventative diagnosis technology is required for
early failure detection in major power facilities.
We provide a variety of monitoring systems capable of monitoring and diagnosing major power facilities in real time
to prevent management negligence or failure, such as transformer gas generation in oil analysis system
/ GIS, Transformer PD monitoring system / Cable PD monitoring system / Generator status diagnosis system.
Type of Analyzer
-
Transformer dissolved-gas analysis system
Measures value of combustible gas generated in insulating oil of transformers during operation. Diagnoses faulty transformers and cause of failure, extends transformer life, prevents accidents and reduces maintenance requirements.
Catalogue -
Transformer PD monitoring system
UHF sensor technology manages transformer life by detecting partial discharge inside the transformer and insulation breakdown of bushing. Detects fine PD signals generated inside the transformer for early detection of internal failures and fine changes, and supports stable operation.
Catalogue -
Cable PD monitoring system
Determines insulation status of cables by measuring partial discharge in power cable Minimizes maintenance cost through precise detection of fault location Generates accurate reports with simple diagnosis of live wire conditions
Generates accurate reports with simple diagnosis of live wire conditions

Composition Diagram
Transformer PD monitoring system function
- Accurately distinguishes PD signal and noise using a PD pattern database
- Detects failure points by automatically calculating PD detection points
- Early evaluation of Initial machine condition
- Diagnoses poor contact, carbonized lead wires, other insulation problems, and internal deterioration of transformers
- Simple user interface with touch screen
Composition Diagram
Cable PD monitoring system function
- Accurately diagnose PD signals caused by initial faults in cables (Reduction of unplanned maintenance costs)
- Identify severity and trend of failure through regular inspection
- Accurate PD occurrence point detection based on the principle of Time Domain Reflectometry (TDR)
