IN-SERVICE TESTING & ASSESSMENT
PD-SMART

Use the Doble PD-Smart for partial discharge testing for all types of in-service equipment including transformers, rotating machines, cables and switchgear.

The PD-Smart works with Doble couplers or your existing, pre-installed couplers.

The instrument is specially designed for calibrated electric partial discharge measurements according to IEC 60270 and has ultrahigh frequency (UHF) capabilities.

Partial discharge activity is one of the leading indicators of insulation health and should be measured as part of a thorough condition assessment program.
