In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over other protection methods. Areas with dangerous concentrations of flammable gases or dust are found in applications such as petrochemical refineries and mines.
Equipment can be designed or modified for safe operation in hazardous locations. The two general approaches are: Intrinsic safety Intrinsic safety, also called non-incendive, limits the energy present in a system, such that it is insufficient to ignite a hazardous atmosphere under any conditions. This includes both low power levels, and low ...
A very simple example is making piping and joints capable of withstanding the maximum possible pressure, if outlets are closed. Limit effects by design, location or transportation of equipment so that the worst possible condition produces less danger, e.g. gravity will take a leak to a safe place, the use of bunds .
For this reason, optional intrinsic safety is fully integrated into the definitions of the Ethernet-APL communication standard. In the technical specification 2-WISE [3] the 2-wire intrinsically safe Ethernet is defined. The intrinsic safety barrier is an electronic circuit at each output or input of a switch or instrument. It prevents ...
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.
