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.
