About the product
- Test capacity of up to 1 0μF – that’s up to 40 km or 25.8 miles of cable at reduced frequency and voltage
- Internal tan delta option with automatic results interpretation
- One minute burn after fault detection
- Automatic frequency adjustment based on cable length
- Adjustable DC pulse rates of 1:3 and 1:4
- IEEE compliant withstand testing for new installations up to 25 kV
- IEEE 400.2 compliant maintenance testing up to 35 kV
- IEC 60229 compliant sheath testing up to 20 kV DC
The VLF Sine Wave 45 kV is a compact VLF sine wave test system with optional integrated tan delta. It is a useful instrument for the commissioning, testing, and condition analysis of medium voltage cables. This unit performs very low frequency (VLF), DC, and sheath integrity testing as well as sheath fault pinpointing when combined with the optional ESG NT step voltage probe. Ideal for both routine testing and complicated diagnostics, the VLF Sine Wave 45 kV has a multi-purpose design with a continuous duty cycle.
For 0.1 Hz sine wave, rectangular, or DC voltage tests, the VLF Sine Wave 45 kV provides enhanced voltage quality and stability. In the event of excessive charge, its current integrated breakdown detection shuts down the test, ensuring limited damage to the cable. Up to 1000 measurements can be stored in the internal memory and results can be viewed on the unit or downloaded via the USB drive to the included Easyprot software for reporting.
An optional internal tan delta test is available that automatically evaluates results for PE, XLPE, and PILC type cables based on insulation and selected compliance standard.

MeggerBook software
MeggerBook & MeggerBook Lite Software
latest version
What’s new in version 4.0.1
Bugfix
- Data export message is now only displayed when the export is completed
- The status of the Online Map checkbox can now be changed
- Fixed an error when saving measurement data sets
- Fixed several design issues and functional inconsistencies
- Fixed several report template errors
- Fixed several problems caused by the template editor's line tool

Improvements
- Extended and improved the rating functions
- Added a pop-up window when saving an empty or already existing cable number
- Added a filter value to the cable detail view
- Improved runtime conversion settings
- Zoom level can now be saved, allowing the user to adjust the curve to the essential point before generating a report
Removed

- Leakage current values are hidden for measurements where no leakage current is measured
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).

Use the following procedure to update the software of the test system:
1. Unzip or copy the firmware image (*.img) and the associated checksum file (*.crc) to any
directory on a USB stick. Make sure that both files have the same name.
2. Switch on the test system.
3. Insert the USB stick into the USB port on the front panel.
4. Open the menu “Settings” > “Admin” (enter password) > “Update”
5. Navigate to and select the directory containing the image file.
6. Select “Accept” to confirm that you wish to perform the update.
Result: The update is performed. Do not turn off the test system during the update! After the update,
the test system will restart automatically.
