Issues with Unintentional Islanding
Personnel Safety – Unintentional islands can cause hazards for utility workers if they assume downed lines are not energized during restoration
Overvoltages – Transient overvoltages due to rapid loss of load are possible. If an adequate ground source is not present in the island, a ground fault can result in voltages that exceed 173% on the unfaulted phases.
Reconnection out of phase – This can result in large transient torques applied to motors connected to the islanded area EPS and their mechanical systems (e.g., shafts, blowers, and pumps), which could result in damage or failure.
Power Quality – Unplanned island area EPS may not have suitable power quality for loads
Protection – Unintentional islands may not provide sufficient fault current to operate fuses or overcurrent relay protection devices inside island
