Tutorial: Insulation Resistance Testing / Megger Testing / PAT testing Pt 2

[@dumptongee]

I don't care what they say about you, I am 75, & although I am not an electrician, I have learned a lot from your great instruction video., even though I wouldn't legally be allowed to carry out these tests, but this gave me a greater in depth understanding. I have now subscribed. Martin UK

[@luisgonzalezl5794]

Keith, this is a topic that I was eager to learn about... You did a great job on explaining in simple terms what an Insulation Test is all about and how it can help us troubleshoot some of the electrical situations that occur on electrical systems...

[@2958918]

never found multi-voltage (step) method explained clearly like this. lots of thanks to you.

[@chuckram2188]

I really appreciate your videos and demonstrations of various brands, types and functions of different equipment available, Your information is meticulously described and very beneficial to technicians like myself, Thank you Sir!

[@jesusjones83able]

Really good video and you got balance between the practical and theoretical perfect in my opinion. Thanks

[@simonsj15]

Wow! Two videos in one day. Thanks Martin.

[@mjlorton]

It's been a busy week Jim! ;-) Thanks for the post.

[@joestallings6993]

Exactly the information I needed. Thank you for being clear. Nicely done.

[@outdoorsadrenaline]

Thank you for these videos it really helped me understand much more than I knew existed.

[@Kebekwoodcraft7375]

Thanks never to late to watch a great informative video , I was interesting to know how insulation tester do , now I got a very good idea , great gob as usual from Mexico

[@mikeadler434]

Another great video! Thank you for taking the time to create it! 👍👍

Good mix of theory and practical.

[@nilendra75]

Nice piece of work, very informative. Thank you.

[@jonobnz7597]

best teacher on youtube. thanks.

[@patrickryan5048]

Excellent, so well explained

[@SonAyoD]

great video. we do alot of meggering cables on the railway with the interlocking

[@Affordanet]

Hi Martin, just wanted to say thanks again my friend. I'm Still enjoying your channel a year later, keep up the good work my friend!!!

[@mjlorton]

My pleasure, thanks for the post. Cheers, Martin.

[@africanelectron751]

Wow that's some proper in depth info right there great video thanks!!

My pleasure, thanks for the post. ;-)

[@melbournian12]

Great work Martin.

[@mjlorton]

My pleasure.

[@ankaboon]

Thanks for the great efforts

[@sivanathan6891]

That's really a great sharing sir very useful

[@anthonynguyen55555]

i have a question about ir testing on light circuit with transformers for the downlight,should i only test between to neutral earth and active to earth,but cannot test between neutral and active because high voltage can damage electronic transformers?

[@MauricioBallarotti]

Thanks for these very good videos.

[@MJ-iy4fb]

Good video. I was thinking there is a way to seclect the proper voltage for the wire. I want so say it was something like 5 times the actual voltage used on the wire.

[@DonOmar991]

Thank you a lot for this rich knowledge you shared..gr8 work !!

[@rotlerin]

Once again - excellent!

[@mjlorton]

Thanks Robert.

[@larryclark9380]

Excellent video. Thanks. Watched two. Now I am hooked.

[@AB-yu2tj]

How would one diagnose a turn to turn short in the winding not shorted to chassis on a single phase 120-220VAC motor? Motor is working but pulls a little more amps. Caps are fine.

[@jafarsaeidi9370]

thank you for your training. But i have Insulation tester from Uni-T U512 and when i want to test the Cables in the all time just show the result of OL and i don't know is is correct or not. and when i want to show the result to any one they don't accept it because of not exact number. could you please share the training for uni-T insulation tester? regards, S.Jafar

[@SuperMan-zc4bq]

Nice tutorial. Thank you Martin

[@jamaicaelectrician]

very informative.keep doing the good work.

[@sumanlovessapanakhamcha5771]

sir, i like ur video so much but i don't understand what reading of resistance in megger meter means that compressor or motor or any kinds of electrical equipment is fail or bad or ground plz,sir explain me plz hoping for ur positive response?

[@dbo8041]

Very helpful. Thank you

[@Lordlytol]

Thank you. Very Informative and helpful.

[@franciscoalvarez5215]

Amazing, brother. Thanks for sharing your knowledge.

[@adam1273123]

Very nice video, thanks for the info

[@mjlorton]

My pleasure, thanks for the post.

[@Samuelpauline008]

good explanation and understanding...thank you sir God bless you

[@reyannruiz8637]

Thank You for a new Knowlegment

[@richardcryer]

This is the most dangerous video I have ever seen. This could get someone killed. Proving dead with a non contact voltage indicator or a multimeter is utterly wrong. The description of the theory for insulation resistance is good. Please update as not to kill someone!

[@vipinv8004]

super explanation

[@sur7810]

very informative..cheers mate

[@mjlorton]

My pleasure, thanks for the feedback.

[@Teefy3]

In this video you said you had planned on reviewing specific insulation testers. I can't seem to find any of your reviews on your channel, have you done any further reviews (on insulation testers)?

[@mjlorton]

Hi Keith, I've not had much time for them yet but I have just done one on the Martindale clamp / insulation meter. In the video I make use of the Fluke, Mastech and Metrel: kzbin.info/www/bejne/hKmlnaytma97e8k

[@Teefy3]

Okay thanks. Great videos btw.

[@robertlane913]

thanks, very well said

[@TheOldmankk]

My two cents. Our newly opened Subway Train Systems behave intermittently due to the poor insulation of many installed signal and power cables. The involved constructor has to replace all with heavy penalty, and many down times and inconveniences completely put off the local commuters. Obviously, many vendors has occasionally failed to complied the submitted Tender's Specifications and also those on-site commissioning officer are simply lazy and failed to carry out their duty.

[@mjlorton]

Interesting post. Thanks.

[@bend0matic]

Perfektenschlag!

[@Martin120577]

Hi mjlorton; I watched a lot of your vids, very nice and very interesting! Im an electrician in the Netherlands and I work around Energy distribution systems Cat III and Cat IV. Lately Im am looking for an affordable Insulation meter wich can measure with 1000V and is accurate with its measurements. I dont have money to get me a Fluke 1503 or 1507 ,so Im looking for something close to the same kind of performance but for less money. For instance , is the UT505a or UT505b of for the same matter a UT 513 any good? the 513 I can get as second-hand but is like new Can you advice a good insulation meter for around E200-E300 ? thx in advance!! Cheers! Martin

[@sarangalekamge1048]

Great explanation. I was not aware of this device. I have a question, does this meter produce high voltage? Can anyone answer me, please?

[@shannonsloan7246]

Yes, it does generate DC voltage. This voltage can be harmful if a person comes in contact. However, because there is very low current most times you will just feeling nasty little bite.

[@fatehyalgobaily8279]

Thank you very much for your nice explanation and I hope that you will explain to us the cable test by device VARLEY, MURRAY

[@sivucit]

Excellent video, waiting for long tme for this kind of video,, in case of USA, earth and neutral are connected together at da board, if so how can i test insulation test between earth and neutral , please advise, because both are connected. any tips, please.

[@jonobnz7597]

disconnect the link between earth and neutral at the board for the purposes of the tests. DONT FORGET TO RECONNECT THE LINK THO.

[@tahir4010]

Very useful

[@dazaro3]

Great video,thanks.

[@mjlorton]

Thanks.

[@amaljacob8917]

good tutorial. thanks

[@quietudinal4857]

How much more effective would be made the teaching point regardigng safety if he removed the gold ring on his finger & wore safety glasses and gloves when demonstrating (even though he runs simulated tests). Seeing good practice reinforces good practice.

[@tonysfun]

Just to let you know, the www.powercet.com/uploads/files/AE_Understnd_Insulation_Res_Testing.pdf isn't working. Also the: ISO-TECH Test equipment: uk.rs-online.com/web/generalDi... isn't working either. I've tested it on couple browsers with the same results. Thank you for your videos!!!

[@hardcooling]

very nice vid.

[@mjlorton]

My pleasure, thanks for the feedback.

[@mariuszsalatka9329]

Another great video. Im really impressed of your knowledge and work on your channel. Good job. Also would you be able to do review insulation multimeters in mid prices like uni-t ut533 (how are them also good on Voltage, current etc) Thanks a lot.

[@mjlorton]

My pleasure, thanks for watching. I'll certainly try review equipment right across the price range. Cheers, Martin.

[@davidtubber]

Wow. Just wow.

[@Bylga]

Thanks for sharing =D

If you live in a country where english is the main language, you shouldnt have to cater to a minority language. They came in our house, let them learn our language.

[@w8lvradio]

Brandon Gillette The simplest thing, I think, is to have French, English, and Spanish on all North American electrical products. Especially good for exports, in any direction.
