Communication base station electric shock
Failure to properly ground communications systems can result in electric shock and/or property damage. . Physical Principle: In humid environments, metal conductors carrying a positive voltage (positive pole) are more likely to attract negative ions from the air, leading to electrochemical corrosion and causing cables and terminals to gradually rust and break. System Design: If the positive terminal. . An effectively grounded system is connected to earth through ground connections of low enough impedance and sufficient current-carrying capacity to prevent the buildup of voltages that may result in undue hazards to connected equipment or people [100]. Good electrical grounding is mandatory, both by local and national electrical codes, but also by good engineering design of your ham station.
