HVI has extensive knowledge and field experience in fault locating and cable testing along with the best tools for the job. Fault locating requires more than just a thumper. Efficient fault locating requires the convergence of knowledge, methodology, and the right hardware. A total approach is needed to get the job done quickly to minimise customer outage time and prevent further damage to the cable system. This includes knowledge of the cable systems design, construction, history, accurate maps, proper fault locating procedures and the right thumper which should include a high resistance fault burn down method, time domain reflectometer/cable radar compatibility, and a top-level acoustic/electromagnetic listening device. HVI can assemble the best system and approach possible to meet all needs from 5kV – 230kV cable.
CDS Series
The CDS Series (Controlled Energy Capacitor Discharge Systems) includes some of the most powerful and full featured fault locators available, including the industry’s top network systems thumper.
VLF/Thumper Combo
The VT-33 is the world’s only combination VLF hipot and cable fault locator, or thumper. It is a complete tool for AC testing and fault locating cables rated up to 25 kV and is TDR/radar ready. It offers a 33 kV AC peak VLF output, VLF cable burn mode, and a 760 J discharge output up to 13 kV.
SKD Series
The SKD Series is a product line of custom-designed and fabricated skid mounted packages with all of the cable test and fault locating equipment needed to equip a trouble truck or cable test/repair van to your specification.
TDR/Radar
Radar Engineers Model 1669 is a portable Time Domain Reflectometer (“cable radar”) specially designed for use with thumpers connected to an arc reflection filter for “pre-locating” high resistance (pinhole) faults in buried primary power cables. This product integrates seamlessly with the CDS Series and the VT-33 thumper.
Accessories
HVI can provide all the accessories needed to put together a complete fault locating system. Fault locating is an approach, not just a thumper. Don’t spend a lot of money on a thumper but not the extra few thousand for a top level listening device to make your efforts more effective. Don’t thump for hours wasting time and damaging your cable when a TDR trace can show you the fault location in two minutes, With the right accessories, sectionalising and pin point location of the fault have never been faster. Consult with HVI on the accessories most appropriate for your situation. We have our favourites but can supply anything needed. For a TDR, nearly any model now available works great.
