Earth-Rite® DGS
Newson Gale’s dual grounding system with system interlocks and visual indication
Overview of the Earth-Rite® DGS
The Earth-Rite® DGS (Dual Grounding System) has two independent earth monitoring circuits that allow operators to earth and continuously monitor two items of metal conductive plant equipment concurrently to 10 ohms or less, such as two bulk transportation vehicles or other metallic vessels like Ex IBCs and metal drums. This feature is commonly used to earth trucks and railcars during transloading operations or to earth up to two trucks or railcars that are being loaded/unloaded at dedicated loading rack installations.
Interlocking the earthing system with the process equipment being used enhances the safety and operating procedure before the process starts. If the earth connection is lost, the Earth-Rite® DGS can shut down the process for one or both of the channels.
Interlocking the earthing system with strobes provides personnel working in the surrounding area with a clear view of when the earthing process is underway and protected.
Dual earthing and monitoring channels
The Earth-Rite® DGS enables the earthing and control of two processes with a single system, using its dual earthing and monitoring channels. Both channels can monitor independent loops to 10 ohms or less from the vessels to a common verified earth bar via an intrinsically safe Ex ia circuit. This solution provides a secure transloading process when transferring materials from one container to another during metering or processing.
Interlock capabilities
The hazardous area approved system can interlock with on-board control equipment such as pumps, PLCs, and valves to prevent the flow of product before reliable earthing is in place, ensuring a safe working procedure is followed prior to any other processes taking place.
Once both the road tanker and rail car have been successfully earthed, all interlocks will be energised and high-intensity green LEDs on the system enclosure will flash, giving the operator the go-ahead to begin the product transfer.
A failure to detect a path to earth of 10 ohms or less at any time, for example by removing the clamp, will safely shut down the transfer of product provided it is interlocked correctly through the PLC or pump control system.
Typical applications
The versatile Earth-Rite® DGS can be used for product transfer across a range of applications:
- Two metal drums
- Two Ex IBCs
- Two rail cars
- Transloading (railcar to road tankers or road tankers to railcar)
- LACT (Lease Automatic Custody Transfer) skids
Installation
Installing an Earth-Rite® DGS system onto the mobile transloader allows a portable earthing system to be taken alongside the process equipment wherever it’s needed.
Certification allows for installation into a Zone 1/21 hazardous area.
