    240 but no earth loop impedance

    I'm testing a job at the minute and today I went to a double socket that has 240 at it but when I carried out a ELI test the result is a open circuit .the 240 I am getting is between L-E and the means of earthing is TT ,it's a radial circuit supplied bu a 20amp breaker totally confused??????

    Loop test with fluke three wire ??

    Can anyone shed any light. Just done loop test with fluke L-N-E setting L-PE. Reading was 8.66 ohms. Have reported high reading to DNO who sent engineer out. He then tested two wire L-E and read 0.13 ohms. this iss not the first time with high reading on my tester and has recently been...

    Earth Faulth Loop Impedance HELP!!!

    Hi can somebody shed some light upon correction factors for earth fault loop impedance. I know that the vales of zs in bs 7671 are if the conductors are running at max temp ie worst case scenario , am I right in believing that if you get a measured result you apply 0.8 to it?

    max measured earth loop impedance query

    Hi guys, Im just filling in my first ever solo EIC when I check the onsite guide and gn3 for max permitted zs (tabulated) for bs60898 type b 32A the table shows 1.16ohms but to me it didnt ring a bell, checking bs7671 table 41.3 shows max zs to be 1.44. Can anyone shed some light on why and...

    T1825 Loop PSC Tester

    I was looking at purchasing the SEW T1825 PSC tester. Has anyone got any experiences with this tester or with SEW testers in general. In my country it's also marketed as a Toptronic T1825 but from what I can tell this is just a re-badged SEW tester. I realise it's not a Fluke or a Megger but at...

    Earth Fault Loop Impedence question

    hello, i got this qustion and would like someone to show me the working out of it please. the measured value of loop impedance for a circuit is 0.83 ohms. if the temperature at the time of the test was 20c and the cable is 70c (factor1.2), what is the correct value. ze = 0.4 ohms

    Test currents applied by a loop tester

    Can anybody advise how much test current is applied when using a 1552 meggar on Zs. Somebody suggests that it could be as high as 6 amp's? Thanks

    The strange loop

    Dear community... I was replacing a light fitting in the kitchen so I had to open up the ceiling rose. There is a cable feeding power that comes in from another rose, the cable with the switch wires.....but there are two cables going from it. One, I assume is going to another light...

    Selling a Megger Lt300 loop tester

    Looking to sell this Megger Lt300 loop tester. Was going through a deceased relatives stuff after he died clearing out the house and found this, still in the packaging so clearly brand new and never been used. I am an electrician myself so i know the value of these can range anywhere from...

    Earth Loop Impedance on a TT system

    Afternoon all, I did a standard Ze test on a TT installation yesterday, and got a value of 215 ohms. The ground is really wet at the moment and so I'm assuming its about as good as the rod is going to get. Would simply replacing the rod with a longer type improve the Ze result? and if not...

    MCB's 230V/110V Zs Earth fault loop impedance values

    I give these out to some of our younger electricians in the aim to get them familiar with such values. Probably old news to most of you fellas but sure it won't do any harm. Calculations from BS7671 anyway, just handy to have a hard copy other than BGB. Cheers John

    2 wire and three wire loop tests

    Bit of an odd one but was doing a EICR today and got some weird loop test results. All low current 2 wire loop tests were around 7-8ohms whilst doing three wire loops on the saner circuits gave more to be expected readings around 0.6-1.2ohms. Overhead supply with a DNO PME head. Any thoughts?
