About the product
- VLF, DC, and sheath fault testing in one device
- Portable thanks to two-part construction
- High test capacitance
- Integrated discharge system
- Reporting
The VLF CR-28, VLF CR-40, and VLF CR-60 are portable, high-performance, and energy-efficient cosine rectangular VLF cable test systems.
Design for testing cables with 0.1 Hz cosine-rectangular voltage according to IEC, IEEE, and CENELEC standards, these test systems are ideal for testing the dielectric strength of cables and joints after installation or repair.
These test systems have high test capacities and yet manage to be compact,because of the patented voltage wave-shape and the power recycling during polarity reversal. Aside from cable and sheath testing, the test systems can also be used for the precise pinpointing of sheath faults (in combination with a step-voltage probe).
There are three portable systems available, each with different voltage levels (28, 40, and 60 kVrms):
- VLF CR-28 up to cable series 15 kV
- VLF CR-40 up to cable series 23 kV
- VLF CR-60 up to cable series 35 kV

Software and firmware updates
MeggerBook Software
MeggerBook Cable & MeggerBook Report Edition Software
latest version
The setup file below is suitable for the installation of both MeggerBook Cable (full version) and MeggerBook Report Edition (free limited version). For further information read the MeggerBook quick start guide
When started with a suitable license dongle plugged into the installation PC, the software starts as MeggerBook Cable 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 .
Without the required dongle the software starts as MeggerBook Report Edition which allows for seamless report creation and offers the same 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 Report 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.
