How much do you know about faults on overhead power lines?

• Faults on overhead lines are categorized as transient, semi-permanent, or permanent
• 80-90% of overhead line faults are transient
• Transient faults are caused by lightning and temporary contact with foreign objects
• Semi-permanent faults may be caused by small tree branches falling on the line
• Permanent faults, such as broken conductors, must be located and repaired before supply can be restored
• Auto-recloser schemes permit successful re-energization of the line after a fault trip
• Sufficient time must be allowed after tripping for the fault arc to de-energize prior to reclosing
• Semi-permanent faults in forest areas are common
• Faults on underground cable sections are permanent faults
• Auto-recloser schemes have substantially improved continuity of supply.
