6 Tangens Delta
6.1 Application
The HVA28TD provides the testing and commissioning engineer/technician with
a versatile high voltage tan delta measuring system suitable for testing medium
voltage electrical insulation systems such as cables (including: XLPE, PE,
EPR, PILC etc), capacitors, switchgear, transformers, rotating machines,
insulators and bushings.
Tan Delta testing enables the cable test engineer to detect insulation defects
before the cable fails in service. The HVA28TD is a HVA test unit with an
integrated tangens delta measuring system. The tan delta test results of the test
object can now be easily measured, recorded and screen on the display. The
results can be stored easily via USB flash drive.
Additional it is the HVA28TD PC Software in scope of delivery. With this PC
Software the test results can be easily stored on a standard PC or Laptop for
analysis, trending or quality control. This enables the cable engineer to now
make tangens delta testing a routine maintenance test.
