    Hello everyone,

    In order to log into this library and access the tools shared by other members it is necessary for you to share your own electrical calculation tool. This is a mutually benefiting effort of ours so that members can contribute their tools and then access tools that other members have submitted. If you have a tool send it to us by mail

    We will then send you the password to access the tools.

     

    Regards,

    @lehoang190873:  Did you already know about load shedding? Use load shedding products? If yes, for what type of usage?

    I remind you that this forum topic is dedicated to discussion about Load-Shedding applications, products …

     

    Don't hesitate also to tell us if you are interested (or not) in getting access to other similar guides as the Load Shedding Guide

    @ Chris480, @ Spir Georges GHALI: yes several manufacturers propose some fault localization systems. Generally, to have a balance between initial investment costs and fault localtion costs, the torroids are installed from the beginning, but only on the main circuits. These torroids are connected to the fault detection modules which enable to know instantly on which main circuit the fault is located. Then maintenance people just have to focus on the secondary circuits of that zone, and use clamp meters to find the exact location of the fault, which is faster and easier as secondary circuits have smaller cables. Of course, it is always possible to install more torroids and fault detection modules, to make the fault detection even faster.

    Yes, energy reduction is really around 40 to 50 times less, and not just 40 to 50%. You can find more information about how they made it possible: just type “tour Elythis” in your search engine (some info are in french only …)

    Hello ally,

    The mail could take some more time as mentioned in the post above yours. Do check your spam folder and if you still do not receive it mail us at engineering@electrical-equipment.com

    Thank you!

    @Leigh: yes, it is precisely the type of experience sharing I have in mind, thanks for sharing it with others. I wonder what kind of measures were taken (or not?) after the accident you describe, to avoid this to happen again. Could you tell us more?

    @all other visitors: please share also your experience here with others, it will help to highlight the risks related to electrical short circuits

    I'm not familiar with AWG cable sizes, difficult for me to tell if sizing is ok or not.

    Did these noises and over-heating appear only recently? If yes, did anything change in your installation recently?

    Some extra questions:

    – Do you know the actual (rms) current going through this breaker? What kind of loads are fed by this CB ?

    – Do you have the possibility to make an infra-red measurement, to show the temperature values around this CB ?

    – Is there any relation between this CB and the transformer you mention in your other topic, which also makes noise? Is this CB fed by this transformer? How are they connected together, cable or busway?

    What I'm thinking about is that you might have a high level of harmonics in your installation, which could be a reason for vibrations and over-heating. Or maybe a connection getting loose…

    current is flow of charge……..the no.of columbs passed a point in one second………is called current

     

    i.e., I=c/s…..current uints are columbs/second (or) amperes…..

     

    for detailed information go through this video……it will be clear those who got dout

    a software from California has been mentioned in another topic of the forum: best electrical calculation software review

    as it is a topic related to LV electrical calculation software, it might correspond to your needs

    Hello,

    A couple of precision about Caneco BT:

    – LV genset source supply is possible at any place in the network.

    – Caneco BT is calculating in normal and stand-by installation configuration.

    – Also Caneco BT multi-manufacturer database integrates technical settings. This allows Caneco BT to make an automatic selection of most adapt cables and protective devices between 10 manufacturer catalogs.

    – Caneco BT also makes Import/Export from/to Excel.

    I keep at your disposal for any further information.

    Hello,

     

    I used Caneco in a previous job, and I was not aware it was possible to place LV Genset anywhere in teh network

    ==> is it a new functionality?

    ==> if not, do you have a demo available somewhere which shows this functionality?

    does anyone here have any experience with EasyPower from ESA??

    it's really good and simple/friendly user programe, but it's more orientated to voltages over 1kV,, e.g. transimission and distribution..

    also, there's free demo version, fully working, but saving and printing/exporting options are unavailable..

     

    sorry for my bad english,, i'm no native speaker..

    cheers,, alen ;)..


    Hello Alen,

    the software you mentioned is for High Voltages, as you said.

    Are you also involved in Low Voltage, and if yes what software do you use today ?
