The Ultimate Guide to Choosing 270V AC Tan Delta Tester

Tan delta, or loss angle testing, is a method to determine the quality of cable insulation by measuring the phase shift between the current and voltage in a cable. A lower loss angle indicates healthier insulation with few impurities, while a higher loss angle shows more resistance from defects like water trees. Test results are interpreted by comparing loss angles at different voltages - a nonlinear increase suggests water tree damage. Standards like IEEE 400.2 provide guidance on loss angle levels to assess cable condition and prioritize maintenance.

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).
