WebIntrinsic safety. One type of protective system used in hazardous locations is Intrinsic safety. There are two categories of intrinsic safety, namely, Category ia; may be used in hazardous area Zones 0, 1 & 2, and category ib; may be used in hazardous area Zones 1 & 2. By definition, an intrinsic safety system will limit the energy Web(r) "Intrinsically Safe" means a circuit or part of a circuit, which is intrinsically safe when any spark or thermal effect produced normally (that is, by breaking or closing the circuit) or accidentally (for example, by short circuit or earth fault) is incapable, under specific test conditions for such purpose, of causing ignition of a specific gas or vapour and an … myf t12sWebSo any barrier/isolator with 28 V safety description will have Co = 83 nF (Zone 0/1; IIC). In practice this parameter will define the maximum allowable cable length. Figure 2 shows an Exia loop with a Co=83 nF. The max cable capacitance Cc=63 nF.
