Mining equipment is typically electrically powered. The trailing cables powering these vehicles need monitoring. The monitoring insures proper bonding of the equipment to prevent hazardous shock potential on the frame. Resistance Grounded systems are also used in mining and should be monitored as some standards require continuous monitoring of the neutral grounding resistor. We will look at a typical mine and where Bender equipment provides Electrical Safety for the Miners.
Key Topics Covered
- Typical Mine Layout diagrams
- Ground Fault Protection, Solid Ground, Resistance Grounded Systems
- Why mines use High Resistance Grounding and Resistance Grounding NGR’s
- Shock and Step potential considerations and standards
- Resistor Failures, NGR Monitoring
- Trailing Cable Protection GFGC
- Electrical safety for battery-operated vehicles in mines
