5 ohms na ang standard ng meralco as many of their electronics need that level of resistance. hindi lang dapat sa substations, dapat sa lahat ng buildings ei ganyan ka stringent ang requirements

is that for the rod only or system?
the 10 ohm i quoted is for rod only buried into the ground and without anything connected to it...
in cases where the resistance is higher, then couplers are used to add length,
a rod usually measured 1.5 meters long and has a diameter of 16 mm,
i am not familiar with local practice though...
on one installation i worked on in Singapore, there were more than 500 rods all interconnected
using 120mm, 70 mm squared grounding wires....
* you simulate a circuit because you know how it works and wants to tweak, not because you want to learn how that circuit works....simulations do not teach you to be circuit smart...it comes with experience....
*do not judge any amp by its schematics, drawing lang yon, look instead at the finished amp, it tells a lot about the amp and its builder.....

i wish i could post drawings and plans for grounding in the plants that i worked on...
yes, they are completely separate....but like i said, they meet at the ground where earth rods are buried for both dirty and clean earths in close proximity to one another....

usually ground separation distance is equal to the lenght of ground rod or ground matting surface area. make it twice to be safe.
