Continuity relay
WebMay 9, 2024 · An earth continuity relay proves that there is a connection to the object to be grounded. One example is the use of two ground cables to ground an aircraft while refueling. Both cables are clamped to the airframe and an intrinsically safe circuit checks that there is continuity through the airframe. WebOnce an earth continuity relay and associated connections of the protection system are installed, the pilot core allows pilot earth loop or earth continuity monitoring protection to function. Refer to r. 5.21 of the Mines Safety and Inspection Regulations 1995 …
