Review System Grounding Requirements
Electrical events like lightning strikes and power surges cannot be prevented. Designing
and installing a good grounding system can help minimize damage caused by these
events. Improper grounding can result in a difference of potential between system
components which can lead to injury to personnel, system failure and equipment
damage.
Figure 12: Site Survey: System Grounding
Masts/towers shall have grounding systems installed. All elements of the tower, fence,
gates and miscellaneous site metalwork shall be bonded to the earth. In addition, the
following areas must be considered in the overall grounding system for the site:
All ground rods are to be driven a min of 150 mm (0.5 ft) below grade.
All bends in ground wire to be well rounded curves free of kinks, twists etc.
Resistance to earth as per the best practices.
An air sector controller (lightning rod) is to be installed at the top of the mast/tower.
Mast/tower components must conform to the following standards.
Lightning Rods: ANSI-TIA-222 F&G CAN/CSA-S37-01 standard.
Ground Rings: ANSI T1.334-2002, Section 5.3.1 and NFPA 70-2005, Article 250.53.
Electrolytic Rods: NFPA 70-2005, Article 250.53 and NFPA 780-2004, section
4.13.2.2.
Ensure all grounding complies with local electrical standards.
The grounding wire may be secured using the cable hanger stack.
