I agree, first check the grounding.   Surge suppressers are useless if they don’t have a good ground to absorb the surges.   Once you know you have a good solid ground you can look at improving surge protection if you are still having problems.

 

Also a good ground conductor out to the tower base.   This will help shunt surges from going through the coax and transmitter.

Just came from a Grounding site seminar by Transtector;   I also know a site similar to what you are describing,  don’t trust your ground system , check it with a ground restiance tester.

A real one, not an ohm meter.  The site I am referring  power co. has  3 xfmers , and 3 wires feeding  a 1000 ft tower tx. Site . bad electrical issues until they , meaning tower owner , pounded in a 4 inch steel well casing

180 ft. down  I think to water table  , grounded tower to that well casing , and all is well.  

No , even  70 ft. ground rods still don’t work when they are in sandy soil , unless they ‘hit something to Bite  {conduct }  into .   Power Co. tried that, and it   didn’t work .

Chemical ground rods are recommended by ground specialist if no ground is possible to obtain  [expensive, and require maintenance]  Ufer grounds are also viable in dry places  of the world ,

 

That’s the news from northern Michigan beach sand county,

Hey All,

 

I’d like to get some suggestions on cleaning up 3 Phase power in the middle of nowhere coming from a co-op. I have surge suppression on the mains and under the breaker with the transmitter but I am still cooking the input side of the 2500w modular power supplies every time there is storm.

 

The large surge suppressor on the incoming electric is older, so I am looking at replacing that since it is probably past its prime in surge dissipation. Are there any other tips/tricks/devices I should look at?
