Superior Handheld Partial Discharge Detector
PDStar
Power Monitoring and Diagnostic Technology Ltd.
PMDT is proud to present one of our latest innovations, the PDStar. It integrates On-Line Partial Discharge (OLPD) testing and Infrared testing for MV and HV equipment, which combines UHF, AE, Ultrasonic, HFCT, TEV, and Infrared testing technologies. It is applicable for online PD testing, as well as abnormal heating and defect detection on all types of substation equipment. PD amplitude, PRPD, PRPS, and infrared spectrums provide critical data for determining the operational condition of electric power equipment. It connects to the PMDTCloud via Wi-Fi/3G/4G to upload test data, download test tasks, and receive diagnostic results in real time. Another uniquely advanced feature of the PDStar is that it integrates with a 100 MSPS (Mega-Samples per Second) HFCT signal processor, which greatly improves the performance for power cable OLPD testing.

Spiral Antenna UHF Trafo
UHF Spiral antenna is a partial discharge sensor designed to receive electromagnetic (EM) emissions from a PD occurring in the monitored asset. It is a broadband antenna with a flat response which makes Spiral antenna suitable in a number of different applications. It has been optimized to operate in a frequency range typical for PD activity and it was designed to provide maximum sensitivity and high gain. Its compact and robust design (passive sensor) makes Spiral antenna the optimal sensor for direct installation on high voltage Transformers. It can be virtually applied in any electrical equipment provided that it has apertures or EM transparent surfaces. Contact our sales department for consulting.

Lock-in Amplifier
UHFLI
The Zurich Instruments UHFLI is a digital lock-in amplifier covering the frequency range from DC to 600 MHz. In addition of providing the highest operation frequency amongst all commercial lock-in amplifiers, the UHFLI also offers the lowest time constant of 30 ns for demodulation, resulting in a demodulation bandwidth of more than 5 MHz. The exquisite analog front end offers a spectacular noise performance of 4 nV/Hz which helps in many applications to keep the signal-to-noise ratios high while speeding up the measurement. In combination with the most innovative instrument control software LabOne, the UHFLI is the flagship of all Zurich Instruments products and represents the state of the art of today''s scientific instrumentation.

Distance Measuring Equipment (DME)
MS 2002
Distance measuring equipment (DME) is a transponder-based radio navigation technology that measures distance by timing the propagation delay of UHF radio signals. The DME system is composed of a UHF transmitter/receiver (interrogator) in the aircraft and a UHF receiver/transmitter (transponder) on the ground. The aircraft interrogates the ground transponder with a series of pulse-pairs (interrogations) and the ground station replies with an identical sequence of reply pulse-pairs with a precise time delay (typically 50 microseconds). The time difference between interrogation and reply minus the 50 microsecond ground transponder delay is measured by the interrogator's timing circuitry and translated into a distance measurement in nautical miles which is then displayed in the cockpit.
