Abstract
A high voltage detecting device has an input terminal for receiving electrical energy and includes a first circuit having a gas filled tube receiving electrical energy from the terminal. The gas filled tube provides a visual indication of the presence of high voltage. A second circuit also receives electrical energy from the terminal and is coupled in parallel with the first circuit. The second circuit provides an audible and visual indication of the presence of high voltage. The high voltage detecting device is contained in a test stick having a housing. The housing includes three compartments for holding the first and second circuits along with a power supply for the second circuit. The two independent circuits in the test stick provide a positive indication of the presence of high voltage over a broad range of transmission and distribution applications.
