What is a solar substation grounding guide?

Abstract: This guide is primarily concerned with the grounding system design for photovoltaic solar power plants that are utility owned and/or utility scale (5 MW or greater). The focus of the guide is on differences in practices from substation grounding as provided in IEEE Std 80.

What is the maximum value of ground resistance for a substation?

Standards issued by ANSI and IEEE do not require a maximum value of ground resistance for a substation. IEEE Std. 80 only specifies the touch voltage and step voltage which must comply with the specified safe limits i.e. Em < Etouch and Es < Estep. The maximum value of grounding resistance (RG) is a recommendation.

What is the maximum value of grounding resistance (RG)?

The maximum value of grounding resistance (RG) is a recommendation. The recommended maximum ground resistance value from the National Electrical Code® (NEC®) NFPA-70 is between 1 ohm to 5 ohm in general for substations, buildings and large commercial installations .
