The 80k-40 measures from 0 to 40kV AC Peak or DC. On the energy side I have only ever used these when measuring sheath voltages on cables as I wanted to know the specific value to compare to my calculations. I have seen these used for checking earthing systems to see if there was a potential rise present due to faults. Outside of that these types of probes were traditionally used for measuring the anode voltages on cathode ray tubes. For work on the actual HV distribution systems we use voltage sticks as due to the safety rules we have to maintain certain distances dependent upon the system voltage. This voltage probe is not physically big enough for that. Up to about 15 kV, they are two probe voltage dividers. Above 15 kV they tend to be single probe capacitive units.
I worked as an industrial electrician many years ago and I used this probe to test for high voltage measurements on certain machines that were equipped with high output step up transformers. . .etc.⚡️
I'm a resindential electrician and I like your videos...I agree with you ,the H,voltage is not a field to pay in..,except qualified personel can work..Electricity has an immense range and different categories..Keep it Up 👍 Subscribed right now...1️⃣
2 Videos yesterday wow! Luckily I don’t work on anything that would require that. 480 is about the top end and I make sure it is de-energized with a NCV before I touch anything.
What would happen if you plugged that into a Harbor Freight multi meter rated for no more than house voltage? Does the danger come from the possibility of it arcing right through the case of the meter?
This type of probe works on a voltage divider principle. This particular one is a 1000:1 probe, so when measuring the maximum 40 kV, the voltage to the meter would be 40V. To get the best accuracy, the meter needs to have a 10 MOhm input impedance as it forms part of the voltage divider. You can use what ever meter you like, but if the input impedance is not 10 MOhm, then the divider ratio will change and the reading you get on the meter will be inaccurate. Prior to CAT rated digital multimeters, these probes were used with analogue style meters without any issues. The majority of the voltage is dropped across the resistor inside the HV Probe, so you will only get arcing if the resistor is dirty or there is dirt on the red insulator tube allowing the voltage to track across the surface.
Great and informative video about a probe I was curious about. Thanks for your honesty. I prefer to never have one but I was curious about it so loved the video.
This Probe is for LOW ENERGY APPLICATIONS ONLY....not for high power circuits.....its intended for HV electronics not for power circuits......I would never use it. If your not a High Voltage Electrician, you should not mess with anything beyond 480V

Good evening sir... could you please do a review on your tool caddy and yellow parts organizer?
Okay

I agree with you 480 is my limit energized. I’ll work on high voltage energized ONLY if it’s a MUST.🤔🙏

It’s difficult to predict what would happen, but I wouldn’t want to be the one who finds out. 🤔🤞
