Common Chassis Ground – isolation between circuit common and chassis (chassis grounded). Isolated Circuit Common – isolation between circuit common and chassis (chassis floating). Isolation measurements are made with the assembly or subsystem unpowered and disconnected from any support equipment.
A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. [1] Examples include electronic instruments and motor vehicles. Usages
Floating grounds can be dangerous if they are caused by failure to properly ground equipment that was designed to require grounding because the chassis can be at a very different potential from that of any nearby organisms, who then get an electric shock upon touching it. Live chassis TVs, also known as hot chassis, where the set's ground is ...
The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices, such as cell phones and media players, as well as circuits in vehicles, may be spoken of as having a "ground" or chassis ground connection without any actual connection to the Earth, despite "common" being ...
Building on an existing relationship, Qualcomm says its Snapdragon Digital Chassis, its chipset, and associated technologies, paired with Google’s Android Automotive OS, will be the basis of a ...
Transformerless "hot chassis" televisions continued to be commonly manufactured long after transistorisation rendered live-chassis design obsolete in radios. By the 1990s, inclusion of audio-video input jacks required elimination of the floating ground as TVs needed to be interconnectable with VCRs, game consoles and video disc players.
In digital electronics, negative voltages are seldom present, and the ground nearly always is the lowest voltage level. In analog electronics (e.g. an audio power amplifier) the ground can be a voltage level between the most positive and most negative voltage level.
