Partial Discharge analyzerThe Doble Lemke PD-Smart is a versatile, multi-application partial discharge (PD) analyzer especially designed for day to day field use. With its easy-to-use software interface and capability to conduct both on-line and off-line measurements, there really is very few places you cant use a PD-Smart. It is well established that partial discharge activity is one of the leading indications of insulation health and should be measured as part of an asset management program.
