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.

Wireless voltage measurement, testing and analytics system

A test verification circuit is described herein for verifying proper operation of a tested circuit, such as a voltage hazard warning circuit, using an N-channel MOSFET configured for switching ON and OFF the test verification circuit during a power outage, and a voltage source that provides an input voltage to the N-channel MOSFET from a conserved power supply.
