Abstract
Official abstract text for this publication.
A system and method for detecting the presence of a voltage on a ground conductor which is coupled to a protective Earth (PE) terminal associated with a power source. The power source is used to apply a voltage to a device. The system may use a high impedance device coupled across a switch, with the switch being in communication with a portion of the device. A control system may monitor a voltage across the high impedance device and determine if the voltage across the high impedance device exceeds a predetermined threshold. Exceeding the predetermined threshold indicates that an unsafe voltage from the power source is present on the ground conductor. A natural high impedance path between the device and the Earth is used to provide an Earth connection through the device to the Earth during operation of the system.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for detecting the presence of a voltage on a ground conductor which is coupled to a protective Earth (PE) terminal associated with a power source, where the power source is being used to apply a source voltage via first and second terminals to a device, the system including: a high impedance device coupled across a switch, with the switch being in communication with a portion of the device and with the PE terminal associated with the power source;…
