Preventing Arc Flash InjuriesAn article in Electric Light and Power magazine describes how utilities can reduce arc flash risk in medium voltage switchgear. The article describes how arc flash risk can be reduced in both existing equipment and new installations.
For new installations the article brings out four points to ensure new electrical equipment provides better protection. These are:
- Specify automatic secondary disconnects, which eliminate opening doors during racking.
- If avoiding remote racking units, order racking motors mounted on each breaker. This allows racking of breakers in and out of the gear without personnel at the equipment.
- Specify magnetic actuated breakers, which limit the amount of service required and limit personnel time near the switchgear.
- Building infrared viewing ports into the switchgear allows routine inspection for hot spots.
