Doble PD-Smart Partial Discharge Analyzer

Partial Discharge activity is one of the leading indicators for determination of insulation health and integrity. The PD-Smart is an effective device specifically designed and calibrated to measure partial discharge activity in accordance to IEC60270 while the high voltage apparatus is in service. The PD-Smart’s extensive yet intuitive control makes it an invaluable instrument for condition assesment programs.
