Power surge killing appliances in Florida

[Gregory Repasky]

My brother-in-law‘s father-in-law lives in Florida. He states that his father-in-law‘s appliances one by one or more, have been destroyed by power surges from time to time. He has not seen a ground rod sticking out of the ground from anywhere around the house. He hired an electrician to change all the outlets and install surge suppressors here and there. Any suggestions or opinions on solving this? This is ALL the information I have, no more. Thanks in advance.

and make sure there is a ground rod driven.

Better have your service and power line checked for poor neutral termination.

Unless there is a Concrete Encased Electrode (CEE) connection to the rebar in the foundation. That is already better than any rod you could drive.
But if you can't tell (cannot follow a ground wire coming to the panel back to where it starts)a rod is a small effort to add.

Or poco problem too!

My son's house had the motor start capacitors in AC/HP and 2 garage door start caps and the control board on induction stove top all fail within 3 or 4 weeks. Plus7 or 10 incandescent bulbs in a chandelier.

Line-line voltage was 268 V when I measured it , thought there were likely higher spikes, and so informed POCO (PSE).

POCO put a recording meter base adapter on the house for a week - the day after they checked the readings on their recorder they were out replacing the distribution transformer, never did find out from poco what the transformer issue was. No failures since then (> a year ago)

Thankfully the refrigerator or freezer did not fail, most electronics nowadays built for 85 to 265 Vac input which is why none of those failed.

When I see voltage that high it is usually POCO has a problem with voltage regulation equipment on their primary side.
