The partial discharge meter PXDP-II is a portable device that performs the detection and measurement of partial discharges in electrical devices or components. Registers partial discharge measurements for analysis and diagnosis through optional software for PC. The PXDP-II can be used in several applications and complies with IEC 60270.
This measurement system is a powerful and flexible partial discharge measurement tool. Early detection of failures in development and timely repair improves the reliability of the network and is a cost-effective way to manage maintenance. The partial discharge test is a powerful predictive and qualitative analysis tool that warns of a possible future failure of the system.
It shows the waveform of partial discharge and incorporates a loudspeaker that reproduces a sound of the measured signal (the equipment records and stores the measurements, date and time of reading).
The use of the equipment has been extended for the diagnosis in industries and laboratories. The PXDP-II is an extremely powerful device for the detection and measurement of partial discharges when used with a high voltage source with a very low noise level and a high frequency capacitive coupler. It is an economic and very precise solution for the detection and measurement of partial discharges in accessories and components such as transformers, circuit breakers and lightning conductors.
This partial discharge meter is the most effective and economical solution for the inspection of splices and elbows in the electrical network.
The use of the PXDP-II can be integrated to be part of a preventive maintenance program, thus avoiding problems and interruptions of the electrical networks. The PXDP-II is a very precise and flexible equipment. Its system of extension to long bands allows an accurate detection of the activity level of the partial discharges. The meter uses a high speed detection technique which allows the equipment to be very powerful. In addition, it is possible to record the download measurement in graphic or auditory form, with the date and time of reading. The equipment allows you to operate your registry in the same location. The recorded measurements remain in memory even when the PXDP-II is turned off, allowing the transfer of these records to a computer.
Diagnostics under tension at the same site of the analysis:
-The PXDP-SOFT software allows to manage and visualize records of partial discharges, downloading the readings from the internal memory of the computer to the PC.
-Metal-Clad boards are easily inspected with the PXDP-II and its accessories:
-The ULD-401 parabolic sensor in the PXDP-II unit detects and locates the corona effect in any device at high altitude, which reveals the presence of partial and contaminant discharges.
-A capacitive sensor detects PD in cable joints and elbows. The capacitive sensor kit is coupled to the reference module (this module allows you to test the sensor before inspecting the cable). Thanks to the handle that is screwed to the sensor, the user wins in safety.
-The PXDP-II off-line kit allows testing a large number of medium and high voltage devices (such as couplers, cables, insulators, transformers, etc.) to detect DP for off-line testing. Rapidly identifies problems of design, manufacturing or operation, improving the design and reliability of the network (which reduces operating costs when installing reliable devices).
As an optional module, we highlight the synchronization module with the phase of the network, allowing to attenuate the noise (important parameter to attenuate to identify partial discharges). The synchronization is designed for TEV, acoustic, with HFCT, splices and elbows, etc.

It is a portable device that allows the detection of partial discharges in cable joints and elbows, circuit breakers, acoustic tests, TEV, rotating machines, etc. It is a user-friendly, versatile, lightweight and portable device; based on PXDP-II technology
The XDP-II-LT has an amplification system of ultra-bandwidth that allows to measure the activity of the PD. The XDP-II-LT shows the PD waveform during the measurement and displays the noise before filtering to help the user recognize PD of the noise (uses a high-speed detection technique).
