Study Notes
Grounding, Bonding, and Electrostatic Discharge Techniques
- Protects both equipment and personnel by implementing proper grounding and bonding techniques.
- Essential for creating a safe working environment as a cyber-technician.
Importance of Grounding
- Grounding connects electrical systems to the Earth or a large conductive body, ensuring safety.
- Main functions:
- Personnel safety
- Equipment protection
- Electrical noise reduction
Personnel Safety
- Grounding electrical equipment and structures redirects dangerous currents to the ground.
- Activates protective devices such as fuses and circuit breakers during faults.
Equipment Protection
- Shields power sources, equipment racks, and structures from transient voltages and currents.
- Prevents damage from brief electrical surges caused by storing or external influences like lightning and ESD.
Electrical Noise Reduction
- Electrical noise (EMI) disrupts normal voltage and current flow impacting equipment performance.
- Noise can originate from devices like vacuum cleaners, causing interference in other electrical devices.
- Even minor electrical noise can harm signals and devices if not managed properly.
Grounding System Requirements
- Careful consideration necessary for bonding metals within grounding systems.
- New facilities must define grounding and bonding requirements to ensure safety and functionality in the final installation.
