Doble launches cost-effective hand-held partial discharge detection scanner

Doble Engineerings PDS100 is a hand-held radio frequency scanner designed to be used in a live substation to find the characteristic signals emitted by degrading insulation

Without the need for outages, this high-tech device can detect partial discharge (PD) in just a few seconds, making it an ideal tool for a condition-based maintenance programme.

Whole substations can be surveyed and analysed with this lightweight, user-friendly tool. The instrument is also sensitive enough to detect internal apparatus problems without infringing on safety areas. It is specially designed to separate radio frequency interference from substation background noise.

The PDS100 is ideal for daily use or during routine substation inspections along with other testing methods, such as infrared scanning.

With the PDS100, operators can record and analyze PD signals, giving them the information they need to make informed decisions on further testing or monitoring needs.

Recorded results can be used for future trending, helping to assess insulation condition of individual assets over time. The PDS100 is a rugged and powerful instrument that should be in the tool box of all service and test teams.
