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 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 🇿🇦.

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.

@arunraj7955 4 года назад

Thank u very useful for this video.

@Robert-ts2ef 3 года назад

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?

@rotlerin 10 лет назад

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.

@mufc99ok 10 лет назад

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

@rotlerin 10 лет назад

I'm hoping the electrician cured the fault - so far so good. If it happens again I'll certainly try this. Thanks.

can we test Ac motor disassembled, I mean the rotor and stator are separated, test only the stator thanks

@ronaldlijs 10 лет назад

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!

@privatear2001 7 лет назад

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!

@kos369 7 лет назад

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?

@seandempsey9396 3 года назад

1 megOhm = 1000000 ohm's

@step9203 3 года назад

eh... 1mΩ = 0.001 Ω, 1MΩ = 1.000.000 Ω, and yes, he wrote it wrong, i think he means 1M not 1k

@simpliciocamirino2271 3 года назад

@wg1948 10 лет назад

Hi thank you , can you show how to see if your boiler is faulty or what part is not working right.

@qzorn4440 8 лет назад

great info and the coffee pot is the most important tool. B*) .

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.

@TheEtbetween Год назад

Magnificent

@friedmule5403 5 лет назад

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:-)

@freeform4480 8 лет назад

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

@ashrafkarjiker6888 2 года назад

What happens when doing insulation resistance test on a stove and oven heating element. Do you have to disconnect the power cord from the appliance

@jamienewman1488 9 лет назад

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
