I finally found out that this unit WORKS AND IS IN PERFECT OPERATING CONDITION.
For sale is a old Associated Research cable fault locator mdl 8613 also known as "thumper". It is labeled HyJoule. Its purpose is to help locate insulation faults in high voltage buried cable, by inducing giant DC pulsed discharges that blast through faulty insulation. The lineman would walk along the buried cable path and feel the "thumps" with his feet.
The way it works is this. The first device is a DC source, it uses about 10A of 120 VAC as supply and produces up to 25 kV DC as output. For safety when NOT in operation, when high voltage is switched off, high voltage side is grounded by a contactor. The second device is comprised of a high voltage capacitor, and a special high voltage contactor to produce periodic discharges. There is also high voltage cable that is supposed to be connected to the cable being tested. I would guesstimate the size of it as 7/8" in diameter and 50 feet in length. There is also about 70 ft of 1/0 welding cable with clamp on connectors to be used for grounding.
This unit works great, charges capacitors and produces pulse discharges. I was able to blow up a very thin steel wire at 1,000 joules, whih produced a LOUD explosion. You can use it to shrink coins, test EMP functionality, compress coke cans, etc.
This is a freight shipment, $100 for crating and delivery to shipping terminal. Free local pickup in Lisle, IL. You pay the freight company directly, freight calculator is for your entertainment only, it is not binding on me.
It is rare that you can find a safely and professionally made complete HV pulse system. Here's yoour chaance of getting a ready made system, rather than angaging in dangerous work of making your own -- and with all safeties built in, it would be more expensive to produce. It was designed for continuous, repeated pulse discharges and its capacitors and contactors are designed for this purpose.
Includes a length of 1/0 welding ground cable and about 50-70 ft of high voltage cable (seen in the back of the unit). Fully tested.
