VLF Sine Wave 45 kV

Test and diagnostics system for medium voltage cables

  • Performs cable withstand testing, cable diagnosis, sheath testing, and sheath fault pinpointing
  • Unique user experience thanks to large colour display with a touch screen
  • Automatic result interpretation according to the latest IEEE 400.2 standard
  • Highest user safety through earth-loop monitoring and breakdown detection

The VLF Sine Wave 45 kV Test and diagnostics system for medium voltage cables is an essential addition to your testing toolbox, providing you with a complete range of testing abilities. In addition to VLF and DC testing, it can also carry out sheath tests and sheath fault pinpointing (in combination with the step voltage probe ESG NT2). In addition, the optional internal tan delta measurement gives you a reliable determination of the aging condition of your medium voltage cables. The intelligent VLF system automatically adapts the test frequency to the cable length, so that even tests on 25 kV cables (up to 25 km) can be carried out easily and reliably.

The well-designed and touch-friendly user interface takes the user experience to an unprecedented level. Training time is kept to a minimum, even with the advanced cable diagnostic procedures.

The setup file below is suitable for the installation of both MeggerBook (full version) and MeggerBook Lite (free limited version).
When started with after adding the electronic license key into the installed software, the software starts as MeggerBook full version which allows for easy and comprehensive data evaluation, data archiving, cable management and report creation. A personal quotation for a certain number of licenses can be requested here . The new electronic license key allows for 3 devices to have MeggerBook full version installed on them.
The dongle key licenses from older versions of MeggerBook are not supported with this newer version. Updated electronic license keys can be requested here for previous customers.
Without the required software license key the software starts as MeggerBook Lite which allows for seamless report creation and offers some of the features as the full version while limiting the data storage options as follows:

•  Measurements, analyses and reports are not permanently stored in the database

•  While cable import and storage are not limited, a maximum of 5 cables can be created using the cable editor  of the Lite Edition


At this time, the software can handle the measurement and test data of the following Megger devices:


Test vans:            Centrix, Centrix City, Compact City, R30, Variant

Test systems:     VLF Sine Wave 45 / 62, VLF CR 40/60, TDS 40/60

TDRs:                     Teleflex VX(-P), Teleflex SX


Note for test systems VLF Sine Wave 45 and VLF Sine Wave 62:


Data of these test systems can only be imported into the software, if the test systems is equipped with firmware version 3.14 or higher. The latest firmware can be found here (VLF Sine Wave 45) and here (VLF Sine Wave 62).

VLF Sine Wave 45 Firmware

Important: When upgrading from a firmware version <3.14 make sure to export all the test data you may still need for reporting purposes to a USB flash drive. Due to a change in the data format, old data will not be available for export after the update!

Installation instructions:

1. Extract the zip archive to the root folder of your USB flash drive.

2. Plug the USB flash drive in your VLF Sinus test system and turn it on.

3. Access the system menu via themenu item.

4. Select themenu item. The USB flash drive is scanned for appropriate firmware and language files which are then offered for selection.

5. Scroll down and select the application file (.img). The firmware update starts and may take a few minutes.

6. After the update has been finished, the system reboots automatically.

7. Perform steps 3 to 4 again to install your preferred language file(s).
