HDZC-1-TR switch state comprehensive indicator is a smart multi-functional comprehensive dynamic switch-simulating and status-indicating device developed for the technology development of medium voltage system. The product collectively indicates the experimental position, working position, circuit breaker status, grounding switch status, operating mechanism energy storage status; with high-voltage-presence indication and locking control, automatic heating and dehumidification and other functions, simplifying the design of the switchgear panel and beautifying the layout. It is a new type of electrical device that perfects the switch status indication function and safety performance.

The VPIS integrated inside this device must be connected to the main circuit via sensor elements which capacitance is marked on the label superimposed. Product performance meets DL/T538-2006 standards within the nominal voltage range. Additional measures, such as masking the display unit, should be used if enhanced lighting is required to enhance visibility.
