Disconnected Neutral
This article describes the most common reason why three phase surge protection systems fail. 

During installation of a surge diverter, the correct connection of all conductors is critical to the correct operation of the device.

Not only does the ability of the diverter to provide surge protection depend on the availability of a neutral reference; the diverter itself is likely to fail even in its passive state.

This paper is best read before installation of any surge protection system.
