21 results about "Floating ground" patented technology

Most electrical circuits have a ground which is electrically connected to the Earth, hence the name "ground". The ground is said to be floating when this connection does not exist. Conductors are also described as having a floating voltage if they are not connected electrically to another non-floating conductor. Without such a connection, voltages and current flows are induced by electromagnetic fields or charge accumulation within the conductor rather than being due to the usual external potential difference of a power source.
