Thanks for taking the time to share your knowledge. As an adult learner this is one of the best explanations of IR that I've seen on KZitem. Looking forward to Part 2

Great graphics! Thank you. IR testing does not give an indication of conductor corrosion or if its ability to conduct electricity is adequate right? Is this test enough to give tenants confidence that main cables powering a house is satisfactory?

Thank you for your efforts in producing this, it's appreciated. Just like your previous ones, it's very well presented and full of theory and real world content. I'm looking forward to the next episode, hopefully not too long away, as I am keen to see where you're last scenario of false positives etc is going as the AV pictures made me think where you were going. Great production. I've got the 1741+, how do you rate it?

Also..... what red lead are you using with the crocodile clip for the resistor clip?

Hi Olly , thanks for the nice comment. Im working on the next one now so hopefully in a few days. 1741+ is a good meter. Its had to go back to Megger though, as it had a fault. The two lead low current test, is a great function. The lead is the one with the test button on it. You need to press the test button when doing IR so using the probe with the test button makes it easier.

Very interesting, surprised to see arcing of two 1.5v batteries.
@JPElectric
2 жыл бұрын
Thanks for the comment w w. That arc was caused by two 1.5v batteries. It did go through a voltage multiplier though to get enough voltage to cause that effect. I wanted to highlight the fact is was battery only, as I did not want people to think it was mains power, and try it for themselves.

What is the test voltage needed for a 4160 3 phase motor, and what is the minimum acceptable IR for that ?

Look it up in the appropriate standard. IEEE 43 is a good one if you don't know.

why would 23mA trip a 30mA rcd?
@JPElectric
2 жыл бұрын
Hi Leyton. RCDs are sensitive devices, and some more than others. On a ramp test, which is a test which gradually increases the 'tripping current' I generally find a 30mA RCD operates around 25mA.
