A tutorial on insulation testing. I cover the different test methods, an analogy on how insulation testing works, safety and the use of insulation test equipment.
In this video:
* What is insulation testing / what is megger testing / what is PAT (Portable Appliance Testing) testing?
* Electrical safety when working in a DB board / breaker box or around high energy circuits.
* Insulation test types: Proof test, Spot test, Time Resistance testing, Step Level Voltage test, Polarization Index (PI) test, Dielectric Absorption
Ratio (DAR) test.
* Leakage currents: conductive leakage current, capacitive charging leakage current and polarization absorption leakage current in a dielectric.
* Fluke 1587 Insulation Meter

Thank you very much Professor. Your lessons are simply perfect. If I was in UK I'd surely support all of your sponsors.
Probably the best explanation on RUclips. Very pedagogical.
It's one in a million video! Very educative and an up to date information everyone in the electrical field can appreciate. Thumbs up!
This video has open my eyes in terms of the Energy Audit services my company offers. Thank you for your help.
Thank you Sir, you're the best. We were using this device at work on an aircraft testing some stuff.I came here looking for some second opinion type of explanation because I didn't understand it quite well but you sir gave me everything I needed about Insulation Testers. Now I'm gonna work with it with confidence.MegaLove from 🇿🇦.
Fantanstic tutorial. Logical, thorough and clear. Thanks!
Great find, I just subscribed. Thank you so much very informative. Love the explanations with the visual and demonstrations.
Always FANTASTIC tutorials!!!!
Amazing explanation. Thanks a lot for this.
Good Video, as usual. Very useful tester for sure.
Great tutorial. Especially, appreciate the safety perspective.
wonderful tutorial . very informative and explicit and easy to follow
Great video. I had no idea about the safety precautions you should take with these types of testing meters. Thanks for the safety tips.
Damn this is pure GOLD. Really impressed by your teachings, thanks for sharing your knowledge! I'm probably going to be surfing your vids for some time in the future, can't wait!
I really enjoy watching your videos Martin , you seem to be able to get your tutorial across very calmly and very informatively , Thank you for taking the time to make these , they are a great help .
My pleasure, thanks for the feedback.
Very interesting! Great video! Thanks Martin.
Awesome video. Thanks for doing this, Martin!
My pleasure Robert, thanks for watching. Cheers, Martin.
You are awesome! Thanks for the tutorial. Better than my test and tag teacher years ago!👍👍👍cheers from Australia
Very very informative video, thanks alot for posting this. Keep posting videos like this in future.
Brilliant video Martin. Had to laugh because since Christmas we have had trouble with our electrics tripping out the main RCD on our consumer unit every time it rained. After extensive testing by an electrician, he found that the central boiler had a low IR and that rain water was coming in through the flue and causing the electrics to become damp. Your video has explained it all. Can't thank you enough.
if that happens again turn off all your breakers then reset your rcd then one by turn back on your breakers it will show you which circuit breaker has a fault on it ok
I'm hoping the electrician cured the fault - so far so good. If it happens again I'll certainly try this. Thanks.
Very good teaching much appreciated. Thanks
Thank u very much for the video it's really helpful
Great job again like always
What a very nice tutorial video 2 thumbs up martin.
Fantastic video there mate. Very clear, well spoken...
Thank you for your time.
encomium23 My pleasure.
Thank you very much sir....expect more videos from you
Thank you, excellent video, information that's vital to your health.
exemplary tutorial. clear and concise. the analogy to water pressure serves the purpose of the tutorial very well.
***** My pleasure Mark. Thanks for the feedback.
wonderful my friend great job
Never knew there was leakage in insulation.I just though it was shorted or not shorted.Good stuff.I work on Air Conditioners and always have circuit breakers tripping.I will use a good tool for resistance testing.
WOW WOW WOW. THIS VIDEO IS AMAZING, I LEARNED SO MUCH. GREAT VIDEO, PLEASE MAKE JUST LIKE THESE!!
Thank you very much, I benefited a lot from you.
Excellent video , thank you so much.
superbly well explained
GREAT TEACHER INDEED. THANK YOU. REGARDS.
Amazing video. Thanks a lot

good way of tutorial to educate the public.
Thanks for the very informative video!
Cheers!!!!Good explantion
I love you. Thank you for your help.
thank you sir for your good teaching...
thank you for sharing
good job ... keep going
How can you check insulation readings on the kettle, if you measure between live and neutral you should get a very low resistance reading and not a high or infinity reading because you are passing current through the heating element? In the case of light fixtures etc, you would remove the lamp/bulb but for appliances such as kettles, driers, etc, how do you check unless you disconnect the heating elements?
Excellent video! Really helpful!
My pleasure!
Hi Martin, I always use 5kV insulated silicone (rubber certified) gloves when handling my HV test gear, they are a bit thick, but I don't leave anything to chance... The mininium voltage I test on is 1.5kV and I go up to 3kV. This is for insulation testing on audio and power transformers. Cheers!
Thanks for the post!
Hi John! Im just revising this nice vid!
Great video, concise, informative and well presented. Have you reviewed any handheld oscilloscopes?
Thank you for good explanation ,great ;)

paul schumann My pleasure Paul.
this helped a lot .... thanks
Thanks. Very helpful and easy to understand.
Orville Edward My pleasure, thanks for the feedback.
احسنت يا مبدع
Thanks alot. Very helpful.
very nice explanation,,,thank you very much for this video tutorial.
jose deejay Batalla My pleasure, thanks for the post.
I am also not wary happy about high voltage, I have some tricks I use, maybe you find them useful.
When I have done as you demonstrates I do always put a single stranded wire from hot to neutral so if anyone turns on the power it will shorten before any power can reach me.
If I can't do that, I do often run a long wire from hot to the nearest outlet with earth, again to prevent me getting a schock!
Thanks for your fantastic video by the way:-)
Great Video
Great explanation. Thanks
My pleasure, thanks for the post.
Hello! Very helpful video! Thanka a lot. Just a notice:
At video 15.10 you mention 1000 Ω as 1 ΜΩ. Isn't it 1 kΩ?
1 megOhm = 1000000 ohm's
eh... 1mΩ = 0.001 Ω, 1MΩ = 1.000.000 Ω, and yes, he wrote it wrong, i think he means 1M not 1k
Amazing. Thank you so much
A good one, Thank you
Great video thanks
Great video! Thanks for making it. I'm an Electronics Tech who was thinking about buying a Megger tester. I was just wondering if you could clear something up. At 14:56 in, you said you'd like to see an additional mega-ohm for each additional 1000V put on the line. But your board says 1000 Ohms, which is a kilo-Ohm, not a mega-ohm. So for 2000 Volts, should I see 2 mega-ohms or 1001000 ohms? Or was it supposed to be 1000 Ohms for each additional VOLT you added above 1000 Volts (making it 2 mega-ohms for 2000 volt input)? Thanks for any additional info on this you can offer. All the best! Appreciate the help!
great info and the coffee pot is the most important tool. B*) .
Great video!
My pleasure, thanks for the feedback Justin.
I really enjoy the videos! Thanks!
mjlorton hi , i have question. my fluke 1587 always measure on display 2,2 Gohm when i am measurement a motor. What can be that?
great video, good information. here in the UK us electricians are not allowed to use a non contact volt probe or a multi-meter to test if the installation is isolated.
we have to use a voltage indicator the is approved to GS38, then we have to prove the indicator with a known source or a proving unit. i personally like my fluke T150, but a lot of the other guys i know like to use the martindale test lamps.
viperfrank Thanks for your post.
I think you are alowed to use a NEON Screwdriver, but its in small print and not suggest... i had to redo my test because o that
+mjlorton hi I asked a question yesterday and have been trying to find answers on the net to it but no luck ..would you mind giving me some advice on my query please
Dickie Licky zszewqs1aaaaaassss1xxxx-
very nice video..we can learn something from it..
Really useful video
merci pour la video
sa était très fructueuse
Very Helpful
Very useful video
May i ask, is Insulation Resistance testing necessary for 12V equipment?
thanks for usefull information
VERY VERY VERY GOOD VIDEO
Great video very educational my college tutor shocked me deliberately with a megger insulation test but I didn't harm me so just wondering is it therfore safe to be shocked by the megger meter or is it the potential risk of being shocked by the circuit you are working on when you say about the dangers? Thanks
I shocked myself with a Megger once. It was kinda funny.
can we test Ac motor disassembled, I mean the rotor and stator are separated, test only the stator
thanks
Just in the final part of the video you mention about grounding the conductor to make sure it's discharged and to not upset the readings. Does you do that before or after the insulation resistance testing ? What I usually do, it's to touch the cable ends with a piece of insulated wire to discharge them.
Excellent
On earth testing you should put 10 Amps thru, which will burn out (blow) a flimsy conductor. I've seen earth terminals to equipment body with just 2 of the 18 strand copper cable in actual contact. Good video thanks.
Good video with nice analogy.
At minute 14:50 1000ohm = 1Kohm not one Mohm.
Hi great video. 1 question please. So do you actually go around the plant, factory, house or building, and disconnect all the equipment like pc's, toasters, bulbs, burglar alarms, etc. surely you will miss something, and then run the risk of blowing up something. pls could u explain
BRILLIANT..!!! Thanks for sharing your knowledge
Pablo Serna Thanks for the feedback.
The more I watch Ur material the more confident I feel .!! U really inspire me.. Well done
thank you for that sharing ,sir,
Well done
Great thanks!
great explanation but i slept in the middle by the way you explained... thanks
Hi thank you , can you show how to see if your boiler is faulty or what part is not working right.
Awesome thank you
can you make a video about Hi pot testing a DUT device under test and why DUT has AC and DC leakage current when disconnecting the earth ground wire?
well done
Do you have a video explaining how to test for Double Insulated appliances? Thank you
