Absence Of Voltage Tester Technology

The procedure for verifying the absence of voltage gets an upgrade.

Absence of voltage tester technology.

Verisafe is the first of its kind voltage tester that determines the absence of voltage with just a push of a button. The verisafe absence of voltage tester minimizes risk by verifying the absence of voltage before equipment is accessed. Although the test portals reduce exposure when verifying the absence of voltage this process working with hand tools via a portal does not meet the requirements of the new exception 1 in 120 5 7 because. The safe way to verify the absence of voltage the verisafe absence of voltage tester minimizes risk by verifying the absence of voltage before equipment is.

The new exception describes an absence of voltage tester avt. It is further constructed to resist factors that could affect its accuracy and functionality such as. When nfpa 70e released its 2018 update a new exception was included that allows avts listed to ul 1436 to be used to verify the absence of voltage instead of a handheld voltmeter. Nfpa 70e requires that the operation of the test instrument be verified on any known voltage source before and after an absence of voltage test is performed in other words connect your meter to an outlet or a proving unit whose voltage you already know and make sure your meter reads the correct voltage.

Verisafe absence of voltage tester. The new language in nfpa 70e 2018 article 120 5 7 states. The permanently mounted test device is different from the test portal interface that is sometimes used with a handheld voltage tester. Verisafe s automated process and single step activation are standardized to avoid missteps in execution and sequence.

The process used by avts today is based on the steps described in nfpa 70e. This 2018 nfpa 70e compliant product automates the required six step testing process in about ten seconds enabling your plant to operate faster safer and more efficiently. Mounting a voltage test station vts at this wastewater treatment plant reduced a 45 minute 2 man lockout tagout loto task down to a 5 minute 1 man loto task. An adequately rated permanently mounted test device shall be permitted to be used to verify the absence of voltage of the conductors or circuit parts at the work location provided it meets all the.

The verisafe absence of voltage tester minimizes risk by verifying the absence of voltage before equipment is accessed making it easier for qualified electrical workers to determine an electrically safe environment in a fraction of the time compared to hand held portable test instruments.
