Technical details and manufacturing context for Voltage Sensors

Definition
Voltage sensors are critical components within Automatic Transfer Switches (ATS) that continuously monitor the voltage of both primary and backup power sources. They provide real-time voltage measurements to the ATS control logic, enabling automatic switching between power sources when voltage thresholds are exceeded or when power failures occur.
Working Principle
Voltage sensors typically operate by converting high voltage signals to lower, measurable levels using voltage dividers, transformers, or Hall effect sensors. The reduced signal is then processed by analog-to-digital converters and sent to the ATS controller for decision-making regarding power source switching.
