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, sectionalizing 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 favorites but can supply anything needed. For a TDR, nearly any model now available works great.

TDR: Time Domain Reflectometer: TDR-1669 from RadarEngineers
Radar Engineers Model 1669 is a portable Time Domain Reflectometer (“cable radar”) from Radar Engineers 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 for pre-locating faults using the arc reflection method. The Model 1669CI offers the Current Pulse method of fault location as well as the standard Arc Reflection method. The 1669 also locates low resistance faults, splices, and opens on a stand-alone basis. Digital radar captures and holds the fault trace at the instant of the thump. Software then automatically positions a marker at the fault, and the distance to the fault is indicated on the screen. Model 1669 is also packaged in a rugged weather resistant plastic case and can be bolted to most hand trucks.

SDAD Super Directional Acoustic Detector from Aquatronics
The SDAD from Aquatronics is an acoustic and magnetic/ballistic detector used in conjunction with a cable fault locator/thumper to help quickly isolate faults in underground primary cables. The SDAD’s main features are direction to fault to help you get to the failure faster, ballistic impulse bar graph to keep you on the cable path, and depth indication after you have located the fault.

X35 Electro-Magnetic Field Analyzer
The X35 from Technology Enhancement Corporation is designed to ease the process of fault location on a primary network system. The X35 detects the impulses from a primary cable fault locator/thumper and are displayed on easy to read LCD screen. This allows you to interrogate the faulted network system while remaining above ground and along the cable path, sectionalizing between manholes without opening them.
