DFA100 for GIS

The DFA100, Acoustic Insulation Analyzer, is our new handheld instrument for acoustic diagnosis of GIS. It is a battery-powered instrument for detection and location of defects in the insulation of GIS systems. The DFA100 includes an acoustic emission (AE) sensor to detect acoustic signals from a range of defects such as bouncing particles, protrusions and mechanical loose parts. DFA100 is a further development of its predecessor DFA, a widely known and accepted tool for diagnosis of GIS

• Portable and handheld tool for inspection and monitoring of GIS
• Condition based monitoring of GIS during commissioning and in-service
• Design and factory testing during manufacturing
• The DFA100 can be directly applied to any earthed component that is associated with apparatus under test

• Rapid results - the DFA100 is quick and easy to configure, giving results in seconds
  
• Reliability and ease of use - the DFA100 produces high quality results with high repeatability, allowing rapid and reliable decision-making
  
• Battery operated - the DFA100 is a stand-alone handheld instrument, which can operate up to 4 hours on one charge
  
• Wireless synchronization - the DFA100 is utilizing a wireless synchronization module for timing PD and mechanical activity against the power system frequency
  
• Selectable settings - the DFA100 provides recommended settings for testing both SF6 filled and oil filled equipment
  
• Rugged and reliable - the DFA100 is an instrument with outstanding durability for field use
  
• Simple, user-friendly PC interface - a simple interface allows the test results to be uploaded to a PC. Previous data and nameplate configurations can also be downloaded to the DFA100
