摘要： 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.

摘要： In order to provide an environmentally secured voltage testing interface, an electrical enclosure box comprising a front panel is herein-described, into which is mounted a voltage indicator comprising a plurality of LED indicators that indicate a status of one or more circuits coupled thereto and monitored thereby. A compact test point device is also mounted through the front panel and comprises an interface comprising a plurality of external measurement sockets configured to receive one or more probes for manual measurement of voltages, wherein each external measurement socket is coupled to a voltage divider that is further coupled to each of a plurality of respective wires coupled to respective LED indicators.
