Technical FAQs 4

What is the rational design of a grounding grid for Mobile substations?

The rational design of a grounding grid is a crucial prerequisite for ensuring the safe and reliable operation of mobile substations. This paper discusses the design of the grounding grid for mobile substations from the perspective of standardized design, aiming to minimize on-site construction and enable rapid deployment.

What is protective grounding in a mobile substation?

Protective grounding means connecting one or more points of a system, installation, or equipment to the ground to ensure electrical safety. Considering the rectangular layout of the vehicle and its equipment, the grounding grid of a mobile substation is best designed as a closed grounding ring around the vehicle’s perimeter.

What is a good grounding electrode resistance for a communication tower?

According to the IEEE Std 142-1991 and IEEE Std 142-2007 (The Green Book), the communication tower grounding electrode resistance of large electrical substations should be 1 Ohm resistance or less. For commercial and industrial substations including cell site and telecommunications sites the recommended resistance to ground is 5 Ohms or less.

What are the standards for cell site grounding & telecommunications tower grounding?

Our cell site grounding,telecommunications grounding and communication tower grounding methods closely follow the Motorola R56 standards and IEEE Std 142-1991 and IEEE Std 142-2007 recommended Practice for Grounding of Industrial and Commercial Power Systems guidelines for cell site and telecommunications sites.
