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?
Tom Leong: Tom Leong of Auckland NZ is keen to promote the safe use of electrical
energy through proper design of systems and equipment. His desire is to see
electrical accidents reduced to an absolute minimum for all users of
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.
