Valves Testing Equipment
-
A PD or PHD Pinhole Detector is ideal as it has an audible alarm which sounds when a fault is found. Additionally, the test voltage can be set accurately, which is particularly important when testing thin linings. A DCCT mains-powered porosity tester can be used if the process needs to be incorporated into a production line

40Gb/s Coherent Receiver
-
The integrated 40-Gb/s DP-QPSK receiver incorporates two 90° optical hybrids with four pairs of balanced photodetector (PD) and four linear TIAs into a single butterfly package. Unlike other technologies in which the polarization beam splitter (PBS) and/or the power splitter (BS) are not included, Optoplex’s receiver includes both of them with the optical hybrids, PDs and the TIAs to offer a fully integrated solution which will benefit users in terms of completely removing fiber routing and the skew management. The integrated receivers work at the symbol rate up to 12.8GBaud/s.

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.

Plastic Fabrications Testing Equipment
-
PD and PHD Pinhole/Holiday Detectors have an alarm circuit to alert the operator when a fault has been located and the required test voltage can be set on the unit's meter. Spark Testers provide an inexpensive means of testing but have no output voltage meter or audible alarm. However, they can test joints even if the backing is not connected.

TEM Antenna
-
TEM antenna is a broadband antenna with a flat response which makes TEM 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 TEM the optimal sensor for direct installation on medium voltage Switchgears and motors. It can be virtually applied in any electrical equipment provided that it has apertures or EM transparent surfaces.

Fibre Linked EHV And Distributed Assets PD Monitoring System
EHV-PDM
-
The EHV-PDM is a PD monitoring system designed for application on critical EHV and distributed assets, where the monitoring point could be many hundreds of metres or tens of kilometres apart. Fibre linked monitoring points transmit PD data over long distances to the main monitoring unit, which then processes the data and displays the results on a secure customer web front end.

TEV Antenna
-
TEV sensor is a partial discharge sensor whose working principle is based on a direct Capacitive coupling with a Switchgears earthed metal case. The two ends of TEV sensor can be coupled magnetically to virtually any opening on a metal Surface. It picks up the electric signal given by PD activity onto the two metallic surfaces. Thanks to its special design has high sensitivity, larger than other single ended TEV sensors. His compact and robust design (passive sensor) makes the TEV the optimal sensor for direct installation on medium voltage Switchgears.
