PD-Smart electrical Applications The digital, highly advanced and multi-purpose Partial Discharge and Diagnostics System PD-Smart is developed for periodic on-line and off-line PD testing on power apparatus and high voltage insulation systems, for both in-house and on-site applications. The compact and rugged PD-Smart allows you to test and analyze rotating machines, transformers, cables and insulating busbars while in service or offline by using an external power resource. It is fully compatible to DIN EN 60270, VDE 0434, ANSI and other IEEE-Standards. Following application fields are possible: » Lab measurements on any type of insulating material and HV components during Research & Development (R&D) as well as for sciences measurements » Quality testing in regard to PD on HV apparatus and accessories during or after assembling/manufacturing » Partial Discharge testing and analysis whilst installation or commissioning of HV apparatus » Partial Discharge Measurements during the complete service life of the equipment (while in operation or during maintenance/revision) Benefits » Highest measurement accuracy and sample rate due to complete digital system. Furthermore the PD charge evaluation with the PD-Smart is fully compatible with IEC 60270, VDE 0434 and ANSI. » Advanced noise suppression tools. Nothing is more problematic than the intereferences caused by on-site noise. The PD-Smart has a variety of noise suppression techniques: » Noise Gating via integrated hardware gating channel » PD Windowing with unlimited number of windows for an easy suppression of phase-locked noise signals » Freely adjustable frequency and filter » Synchronous measurement. The system can be easily extended for truly synchronous multi-channel measurements. The Star-Diagram helps to differentiate various PD sources and noise from each other. While measuring three phases simultaneously, the combined results are displayed in the Star-Diagram. » Smart User Interface. The new smart user interface represents over 40 years of Lemke's knowledge in design of measurement equipement. Each user can now customize the layout of the dashboard to his personal needs.

PD-Smart electrical be easier, faster and a great experience. » Well-known and advanced Lemke Noise Gating Technology. The PD-Smart provides one separate channel for real hardware gating. The elimination of external noises happens via a separate antenna (gating sensor L110). These features are already included in the standard PD-Smart delivery volume. No other units are needed and thus no extra charge will apply. » Ruggedized and easily transportable. The PD-Smart is self-contained in a rugged polyurethane case and is especially designed for the day-to-day field use. The PD-Smart comes with...
