Technical details and manufacturing context for Isolation Barrier (if required)

Definition
Within a Voltage Sensing Network, the Isolation Barrier (if required) serves as a critical safety and protection component. It creates a physical and electrical separation between different voltage domains or sections of the sensing circuit, preventing unwanted current flow, reducing noise interference, and ensuring operator safety when accessing or maintaining the system. Its implementation depends on specific application requirements and safety standards.
Working Principle
The isolation barrier functions by creating a high-impedance path or physical gap between electrical circuits. This prevents direct electrical connection while allowing necessary signal transmission through isolation methods (optical, capacitive, or magnetic coupling). It blocks common-mode voltages and ground loops that could compromise measurement accuracy or create safety hazards.
