variety of sensors
Integrated camera and QR code scanner
Easy to use via keypad and touchscreen
Reporting via MeggerBook RE software
DESCRIPTION
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.
