Earth Fault Loop Impedance Test




What do you think about this video?

bundeligafan: GREAT VID!!

Instrotech Ltd: Good morning all, hope you had a good week. Here is a short video about an earth fault loop impedance test,

akilgohar: Very well Explained, very easy to understand it. Please let us show the Metter as well, so that we could use the meter as well. that why we use this much of volts to throw in a test, and why we choose it. etcetc. otherwise, video is explained n a good manner. Thank you.

Lisa K: Excellent Thank u

Michael Sarsfield: I am studying the OLCI City and Guilds level 2 plumbing course and after searching the net for a simple to understand explanation for ELI and being totally confused, I have to say that your description is the only one that I could understand. Thanks for a great video.

B0M0A0K: Good video. How do you go about rectifying the problem of having a higher than accepted reading?

Paul Barnes: Chris,, very good teaching,,,question for you how is it you never mention the Rule of Thumb?? 8% My tester is brand new and up todate calibrated and everything,,,now your reading and the table reading is the query,,,your reading 0.37ohm and the table says 1.16 so well within the range,,, however if you apply the rule of thumb the reading comes down to something like 0.92hm do we need to apply the rule of thumb if our tester says its a pass?

codecageadmin: Chris, nice unrushed clear explanatory videos, the books make things seem so much more complicated than they actually are! I'd like to see you taking the Megger MFT1700 series multitester and completing the entire range of tests with the one meter as most people will now be purchansing all in ones' (as i have). Thanks for these great videos!

chriskitcher: With a high Zs reading you could consider fitting an RCD, however you should investigate the reason that the reading is high first. If the cable is too long you may have other issues such as volt drop and short circuit current disconnection time.

EMT: Thanks! They sometimes skip corners and take the easy way. If they ever did that, I suggest you consult with a paralegal or lawyer. This way they won't be able to cheat you.
