More Information
Summary:A permanently installed absence of voltage tester (AVT) may include a connectivity verification system for verifying the connectivity of system cable leads to the main power lines in electrical equipment. An installed AVT may indicate whether the electrical equipment is in an electrically safe state without first requiring direct access to the equipment. One step in the AVT test procedure may include connectivity verification by the connectivity verification system, which may include a sub-procedure to confirm that the installed AVT is directly coupled as intended with direct connection to the equipment being monitored. The connectivity verification system may validate that the AVT is measuring the actual voltage on the power lines of the electrical equipment and has not registered a no-voltage condition due to an unknown disconnection error or installation failure.
