Very cool that the company helped out to sell you just the board. So many companies are trending toward ultra consumerism and planned obsolescence so they don’t even bother cataloging the components with intent to sell for repair. They may be documented in a parts diagram but good luck ever finding it available. Great fun test with the capacitor, very interesting to actually see the point where it arced.
Companys would LOVE to send you a new board for an instrument they sell and it would only cost xxxxxx dollar, but they can pay for shipping. So I wonder how much that card cost.
These are awesome instruments. Would love to see a video on X- (for application accross mains) and Y (for application between mains and PE) rated caps and their supposed failure modes.
Nice! Love it when the manufacturer is willing to go the extra mile to support the end consumer with the ability to buy individual internal assemblies. Really impressed you got schematics too! I have a similar Vitrek unit which had faulty output HV relays (contacts sputtered themselves all over the glass after many thousands of cycles), I emailed them but they never responded. But they did put me on their marketing email list... (idk maybe I said something wrong) Ended up just designing a mod PCB to install new relays on the existing PCB, works a treat now! Interestingly the overall architecture of the Vitrek unit is very similar to this one, they even have a similar PCB that isn't populated with certain components like you noted in this unit at 2:40, in the Vitrek its because they only use the lower PCB for the AC only model, the AC/DC model needs the extra PCB on top with rectification and smoothing.
Wow I have never seen a piece of equipment like that !!! I love this channel. You have the most exotic equipment I have ever seen. You have an incredible home lab and you must have lots of storage space. Just like Curious Marc and his NASA stuff. Glad that Pooch was able to get in on the action !!! There seems to be a piece of test equipment for almost any parameter that can be measured. It is just a matter of locating it. Also enjoy the RF stuff you do. Keep up the good work.
i'd love to see you test how the different AC mains rated filter caps (X and Y) breakdown -as well as other types like normal ceramics and modern solid electrolytics-, and if you can get your hand on some cracked RIFAs to see what happens to them
@@jakubniemczuk then why not use higher frequency similar to flyback transformers? 400hz seems very specific and doesn't sound that high to make much of a size difference
Several times more that what is printed on them. Eg. an 600V UL certified cable won't break down even at the maximum 5kV. A new one that is. PVC insulation does not seem to degrade much over time, but would be interesting to see an older rubber insulated cable, I bet that it will leak or arc over at way lower voltage.
Got a new board from the manufacturer them self, that had to cost a pretty penny and I would not have been surprised if it cost almost as much as you paid for the analyzer.
Would've been interwting to see a second test of the capacitor to see what voltage it would break down at, or if it would even hold its rated 1000 V at that point.
Most of the Hypot series are made to be used inside a safety enclosure with an interlock switch which can plug into the back of the unit. Might be a good idea to make one yourself for the sake of lab safety. As you said, these units are dangerous and all it takes is one small mistake.
Yepp... During the first test I was a bit itchy as that white test lead was a bit too close to the start button for my likeing. Some test fixtures, beyond the electrical interlock, also mechanically ground the hot wire while opened. These devices are dangerous, in industrial environments, operator training and usually certification is mandatory, as well as fencing the test area beyond a certain power level. Even at these lower power levels a clearly marked and clear test area is required. Visial and/or auditory warning signal is required when the high voltage is present.
I wonder if this could be used to analyse the breakdown of HV across coaxial cable? RF at 1000w (watts) or more over say Andrew Heliax coax will carry substantial high voltages but obviously higher frequency AC (the equivalent), however, knowing the breakdown between centre conductor and shield over the dielectric would make a really good test and determine if bends in the coax not only change the characteristics (impedance) but potential breakdown areas. A tight bend I feel would lower the isolation quite a bit. This could be performed over a video using RG174 right up to RG213 and LDF4-50A. Even thicker is used in cell towers and it would be interesting to see the breakdown if possible. Please!!

A "nice bit of kit" and a good video. Thanks. Well-worth watching too!
Quite a dangerous instrument. Also, quite a flexible instrument having such a huge range.
Nice instrument. Glad they could help with providing the board.
PoochAC, PoochDC and PoochGND :)
6000V will "pooch" just about anything. :-)
I'd love to see what the inside of the 20 kV cap looks like.
I found a cap with this exact spec on *liexpress and it's 1/8th the size 😭😭😭

400hz is an aircraft frequency FYI
What's the reason they are using 400hz in an aircraft
The transformers and some other elements can be smaller.
@@jakubniemczuk then why not use higher frequency similar to flyback transformers? 400hz seems very specific and doesn't sound that high to make much of a size difference
@@Rubacava_ The higher the frequency, the more core losses, so it is just a compromise all around, as with all engineering.
@@Rubacava_ it is an old standard from the analog days that got calcified like 50/60 Hz for the grid and 16.7 Hz did for some railways
Would be nice to see cable insulation breakdown voltages, I have always have my second thoughts if they really are what the printed text states.

شكرا على الفيديو❤
Repair videos are the best!
Great video as always. It might be worth correcting the typo in the title (Hypo*t*ultra) in-case anyone is searching for this instrument.
Fixed! Thanks!
Love how the thing has 4 different banana jacks
"Let's put 6000 V on a 1000 V capacitor!" Is this The Signal Path or ElectroBOOM?
Or photonicinduction ?
@@benoitgrange3479Be it high or low voltage destruction, nothing comes close to Photonicinduction. 😄

Shahriar should try a capacitor from Supreme Equipment, they are good for 30Kv.
I liked the flashing red light of death (FRLOD).

Very good question, I would love to see this as well!
I would not have any useful tasks for that Analyzer...but I want one
Cool 🙂
