Surge Damage After a Storm

Lightning does not have to hit anything to destroy a control board, and a gate sitting at the end of a long low voltage run is the most exposed electronics most properties own. The storm damage pattern seen at Pearland Gate Repair, TX Chimps Inc repeats every summer, because a Pearland metal fence line acts as a collector for every strike within a few hundred yards.

How the Energy Arrives

Induction into any long conductor near the strike, a rise in ground potential that pushes current up an earth connection, or a surge down the incoming mains. All three reach a gate controller, and the low voltage sensor wiring is often the path nobody protects.

What Usually Dies

The control board first, then the receiver, then the loop detector. A photo eye at the far side of the opening is frequently taken with them because its cable runs the length of the fence. The motor itself usually survives, which is why the repair is electronic rather than mechanical.

Protection Worth Fitting

A surge arrester on the incoming supply at the cabinet, a separate one on the loop and sensor lines, and a proper ground rod at the post rather than a connection back to a distant point. Each is inexpensive next to a board, and together they stop most of what a nearby strike delivers.

Grounding Done Badly

Two earth connections at different points can carry the potential difference between them straight through the equipment joining them. One good ground rod near the cabinet, with everything bonded to it, is better than three scattered along the fence. This is the detail most often wrong on an installation that keeps losing boards.

After a Storm

Test everything rather than only what is obviously dead. A keypad that still lights may have lost its radio. An operator that runs may have lost its obstruction sensing, which is a safety problem masquerading as a working gate. Cycle the leaf and deliberately test each safety device before leaving it in service.

Insurance and Records

Photograph the damage, note the date and the storm, and keep the receipt for any board. Repeated losses at one address are usually a grounding fault rather than bad luck, and the record is what makes that pattern visible after the second or third event.
