EMS ELECTRICAL MANAGEMENT SYSTEM
Would be a better term for these gizmos.
An isolation transformer coupled after a ferroresonant voltage correction device is a true surge protection unit. From high frequency transients to continuous out of spec line voltage such a product protects against "surges" by any definition.
An LO to earth ground audio screamer would announce L1 Lo reversal.
And anyone connecting to a STANDARD generator without Hertz and Voltage monitoring before throwing the switch, is foolish.
You are pretty smart. BUT, in this case WRONG. EMS is MANAGEMENT not PROTECTION. Doug
