Good. Can you tell if we can calculate Ze by any method? For example in the external fault loop path, one transformer winding leg is involved ( this can be found from name plate data),also length of line from transformer to consumer panel is known,and so you can find its impedance from tables, then from the consumer panel up to transformer grounding rod there is a cpc, and it's length and size being known, so you can find its impedance ,so can we add the above 3 things and get Ze.please discuss it. ,
Hi, very good and clearly explained video. However I have a suggestion, the maximum permitted value Zs should be taken from OSG Table B6 because it is a measured value not from BS7671 Table 41.3 page 62. Am I right? if not can you explain, please. Best regards Michal
This was a lot clearer than how my teacher explained it thanks.
Great video, well explained and good example. Thanks
What do you make of sparky ninjas video saying you can't calculate zs by this method as its not reliable???
how did you do it can you share with me , thank you
