Ground-fault is the most common fault in PV. If not properly protected, ground faults in PV arrays could result in large fault currents which may increase the risks of fire hazards.
The NEC (National Electric Code) states that grounded (Article 690.5) and ungrounded (Artilce 690.35) PV arrays shall be provided with a ground-fault protection device to reduce fire hazards.
This technical paper covers:
Definitions of ground-faults
Causes of ground-faults
NEC standards for ground-faults

Damage from electrical surges is one of the leading causes of electrical equipment failure. Most surge spikes originate from within the facility itself. Any facility with motors stopping and starting, light load panels being turned on and off frequently and other potential power disturbances is at risk for damage caused by a surge spike.
The following articles will provide insight into how to select and specify surge protection.
