VLF CR-28, VLF CR-40 e VLF CR-60
Sobre o produto
- Teste de falha de VLF, CC e de blindagem em um único dispositivo
- Portátil graças à construção em duas partes
- Alta capacitância de teste
- Sistema de descarga integrado
- Relatórios
O VLF CR-28, o VLF CR-40 e o VLF CR-60 são sistemas de teste de cabos VLF cosseno-retangulares portáteis, de alto desempenho e com baixo consumo de energia.
Projetados para testar cabos com tensão cosseno-retangular de 0,1 Hz de acordo com as normas IEC, IEEE e CENELEC, esses sistemas de teste são ideais para testar a resistência dielétrica de cabos e juntas após a instalação ou o reparo.
Esses sistemas de teste têm alta capacidade de teste e, ainda assim, conseguem ser compactos, devido à forma de onda de tensão patenteada e à reciclagem de energia durante a inversão de polaridade. Além do teste de cabos e de blindagem, os sistemas de teste também podem ser usados para a identificação precisa de falhas de blindagem (em combinação com uma sonda de tensão escalonada).
Há três sistemas portáteis disponíveis, cada um com diferentes níveis de tensão (28, 40 e 60 kVrms):
- VLF CR-28 até a série de cabos de 15 kV
- VLF CR-40 até a série de cabos de 23 kV
- VLF CR-60 até a série de cabos de 35 kV

Atualizações de software e firmware
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
- Added a mechanism to clean up the segments database table
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
- The Rating and Result fields are now removed from TDR analyses
- 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).
