Megger-PD Scan
Defects in medium and high voltage systems not only require costly repairs, but can lead to failures of network sections with corresponding consequences. Therefore, it is in the interest of all network operators to recognize signs of impending defects as early as possible and to be able to take appropriate countermeasures on time.
With the PD Scan, Megger offers a lightweight, robust and portable PD scanner that can quickly inspect various types of equipment for partial discharge signals.
The PD Scan is used for the early detection of partial discharges emanating from defects in medium voltage switchgears and other electric equipment. For this purpose, the device has two internal sensors (TEV, airborne acoustic) and can also be operated with various types of external sensors (TEV, HFCT, airborne acoustic, contact probes).
The operation of the device is simple; it can be controlled via the three soft keys as well as via the intuitive touch display. Thanks to the auto-recognition of the connected external sensor, malfunction operation, as well as bothersome browsing through individual screens, can be eliminated.
Thanks to the large variety of sensors, the PD Scan can be used for multiple application ranges. PD within the cable insulation can be detected using the HFCT sensor. Partial discharges in encapsulated switchgears can be measured by using the contact-probe sensor and corona and surface discharges in MV and HV systems can be identified with the parabolic acoustic sensor.
Besides the partial discharge sensors, also a temperature and humidity sensor will be supplied. This is very important as the temperature and humidity can have a significant impact on the partial discharge readings. One of the advantages of the PD Scan is that the sensor is connected directly to the device, meaning data is stored within the test files, removing the need to manually add them later on during the reporting stage.
The variety of sensors have made this handheld scanner a unique measuring device. To support the end user, measurement data will be automatically evaluated and interpreted, and pictures of the identified defects can be made and directly integrated into the report by using the integrated camera. Furthermore, the QR code scanner can directly take over the switchgear/asset data; there is no need to inconveniently rename the folder for each different test object. Make life easier by reducing the number of loose cables in the workspace through using the optional (and comfortable) Bluetooth® headset, which can also be used with a helmet.
Establishing detailed and individual test reports can be performed quickly by using the supplied MeggerBook RE reporting software.
