Substation Grounding
Substation Grounding
(OP)
We are doing a substation design for an Uility company, we are planning to specify the followings:
A surface layer of > 3000 Ohm.M and >150mm thick and 50mm Diameter shall be applied to reduce human body current
Step and Touch Voltages shall be limited to table 52 of CEC per the body of 50kg.
Any comments would be appreciated.

See IEEE Std 80 for design guidance.

I was in doubt about that statement. I went through IEEE 80 and It was clearer to me.

the fence is covered with 150 mm of crushed stone having a resistivity of 3000 Ω •m. Resistivity of the sample Ω •m is provided in IEEE 80 Table 7.
