Doble offers a complete line of partial discharge (PD) testing solutions. A thorough condition-based maintenance program should include a selection of equipment for the detection of partial discharge in high voltage apparatus. Following the initial detection of PD, the results can be further verified by high precision off-line techniques and appropriate corrective action taken.
The PDS100 provides complete substation PD survey capabilities. By simply walking around HV apparatus, sources of PD and external interference can be detected and identified. Routine RFI surveying will assist in locating PD activity while the apparatus is still in service.

Learn more about the PDS100:
The Doble PDS200 is a combination survey tool that uses radio frequency interference and electromagnetic interference diagnostics to find signs of partial discharge.
This hand-held instrument is an ideal tool for a condition based maintenance program, allowing you to quickly find insulation defects in motors, generators, transformers, cable terminations and additional substation components.
With the PDS200’s dual capabilities, you can now to test for PD in the EMI frequency range, which can provide better sensitivity when surveying apparatus at or below 25 kV.
The DFA100, Dielectric Fault Analyzer, is a handheld, battery-powered instrument for monitoring non-intrusive, in-service acoustic signals produced by partial discharge and loose components.

The DFA100 for GIS is a hand-held instrument for acoustic diagnosis of Gas Insulated Substations. 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 AIA, a widely known and accepted tool for diagnosis of GIS.

The DFA100, a hand-held instrument also 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.
