The primary function of an equipotential bonding connector is to facilitate and ensure an equipotential state among various conductive components within a building, thereby eliminating or significantly reducing potential differences between different conductors. This process is crucial for preventing electric shock accidents, mitigating electromagnetic interference, and protecting electronic equipment from damage caused by transient overvoltages.
When the potential difference across the connector exceeds a specified peak voltage limit, the connector becomes conductive, forcing the potentials of the connected grounding elements to equalize. This eliminates discharges between grounding elements and prevents hazards to personnel and equipment caused by excessive ground potential differences. Under normal operating conditions, the equipotential bonding connector remains in an open-circuit state, preventing mutual interference between different grounding elements; however, it activates during events such as lightning strikes that cause potential imbalances, forcing the ground potentials to equalize.
A potential equalization system is formed by combining a reliable grounding system, metal bonding conductors, and equipotential bonding connectors. During the brief duration of a transient event, this system rapidly establishes equipotentiality among all conductive components within the protected area.
PD equipotential bonding connectors are primarily used for equipotential bonding within grounding systems. They feature low voltage limiting levels, rapid response times, low residual voltage, no follow current, and ease of installation. They protect equipment that cannot be directly grounded while preventing damage from induced lightning strikes and voltage surges.
