    Circuit isolation, also known as galvanic isolation, prevents direct current (DC) and unwanted alternating current (AC) signals from passing from one area of a system to another area that needs to be protected.


    Among its uses, isolation maintains signal integrity of the system by preventing high frequency noise from propagating, protects sensitive circuitry from high-voltage surges and spikes, and provides safety for human operators. To ensure human safety, industrial standards require reinforced isolation — that is, twice the basic level of isolation needed for proper operation of the equipment.
