DFA100 for Cables

DFA100 for non-intrusive diagnosis of high voltage cable terminations and cable joints.

Applications

The DFA100, Acoustic Insulation Analyzer,is our new handheld instrument for diagnosis of cable accessories. It is a battery powered instrument for detection and location of internal Partial Discharge (PD) in the insulation of cable accessories. The DFA100 includes an acoustic emission (AE) sensor and an acoustic wave guide consisting of insulated hot sticks.

  • Potable and handheld tool for in-service inspection and monitoring of cable accessories
  • Quality assurance of new cable accessories during commissioning
  • General purpose tool to detect internal PD on other equipment, such as instrument transformers
  • The DFA100 can be applied on live equipment - provided compliant with local safety regulations
