VLF Series -
High Voltage Inc.
VLF hipots perform voltage withstand tests and provide the voltage source for diagnostic cable testing. There is no better method for verifying the AC integrity of a cable than applying VLF AC voltage. Tan delta and partial discharge measurement accessories are frequently purchased along with VLF equipment to extend their capabilities.

Shanghai Himalayal Co.
Diagnostic test that indicates the degree of cable insulation degradation. Rather than using only a VLF instrument to perform a go/no-go proof test, the Tan Delta, used in conjunction with a VLF hipot, permits the user to grade the deterioration level of many cables in order to prioritize replacement, rejuvenation, or to determine what additional tests may be useful.
-
PDIX Series -
High Voltage Inc.
PDIX is a combined partial discharge and tan delta cable diagnostic testing system. By combining HVI’s VLF products with PDIX products, users can perform VLF AC withstand, partial discharge detection, and tan delta measurement on medium and high voltage cables, rotating machinery, and other apparatus with one integrated package fully supported by HVI & PDIX.

HVA28TD -
HV Diagnostics Inc.
The smallest VLF /DC unit on the market now includes an integrated Tan Delta measurement system to perform advanced electrical insulation diagnostics. For example, this can be extremely useful when performing advanced diagnostics on cable systems as it provides valuable information as to the condition of the cable insulation and shield.

Megger Group Ltd.
Cable testing can be broken down to different steps of the process, starting with a time domain reflectometer test to look for an incident signal on the line or, in some high resistance situations, VLF testing. These tests will identify a fault, allowing you to move on to pre-locating it. In some low resistance faults this will occur alongside the identification via the TDR.

High Voltage Inc.
For non-destructive diagnostic testing to determine the quality of a cable’s insulation with minimal risk of failure, HVI recommends tan delta and partial discharge testing for valuable diagnostic data about cable insulation integrity. Both use a VLF source to perform elevated voltage, off-line testing. Tan delta testing measures insulation health, while PD identifies specific problem areas and assesses their severity.
