WebTo be intrinsically safe (I.S.), Zener barriers must be connected to a dedicated I.S. ground. This ground wiring must be run separately, i.e. in separate cable trays – which costs money to create and maintain. Understand the difference between a Zener barrier and an intrinsically safe isolator. WebIntrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In …
