Abstract
In order to mitigate a shock hazard for a user analyzing a high-voltage circuit, a system is provided that facilitates quarantining a shock-hazard high voltage within an electrical panel while providing a safe low voltage to a voltage detection indication device for visual inspection, the system comprising; a voltage conversion module (VCM) that receives input voltage from one or more monitored high voltage lines and reduces the received input voltage to below a predetermined voltage level that does not pose a shock hazard to a user; a voltage detection indication module that receives the reduced voltage and provides a visible voltage indication to the user; and a removable data transmission cable the connects the VCM to the voltage detection indication module.
