TD-Smart Applications Dissipation factor and capacitance testing on: » Motors and generators » Motor bars and generator bars » Power transformers and transducers » Cables » Capacitors » Any other power apparatus or insulating material » No manual and time-expensive balancing (e.g. Schering-Bridge) required. The TD-Smart allows a very fast and fully automatic balancing due to its advanced digital signal processing FPGA hardware. » Small, compact and rugged design for stationary and on-site use. » Complete electrical insulation between the acquisition units and the control stations via FOL-cabling. This provides superior safety in high-voltage set-ups. The fibre-optic links are extendable up to a distance of 20 km. » The PD-Smart delivers comprehensive information not only about actual values of dissipation factor and capacitance but also about magnitude and frequency of the test voltage. The Doble Lemke PD-Smart has a graphic user interface that displays the time dependent trend of dissipation factor and capacitance as well as time function of the test voltage. » Integrated battery for stand-alone use. No further units are necessary. » Outstanding measuring accuracy of the TD-Smart. This is proved and certified by SP Technical Research Institute of Sweden. System data: » Input frequency range: 10 Hz ... 400 Hz » Input impedance: 50 Ohms » Input current range: 50 µA ... 100 mA rms » Additional external shunts: 5 A, 25 A, 50 A (optional) Doble Lemke GmbH Zschoner Ring 9, 01723 Kesselsdorf / Dresden Germany www.doble-lemke.eu Doble Lemke AG Kaiserstrasse 9, 4310 Rheinfelden Switzerland www.doble-lemke.eu
