[WISPA] Lightning Surge Suppressers
I have some Altelicon glass tube lightning surge arresters. I am trying to figure out how to test then to see if they are good. I have used an ohm meter to compare a new one with an old one I suspected to be bad but all reads the same. The replaceable glass tube measures open on bothe old and new.

Re: [WISPA] Lightning Surge Suppressers
Mark, I doubt the ohmeter will tell you anything. The gas tube is supposed to measure open. It's job is to conduct only when lightning needs to be shorted to ground instead of going through your equipment. Put the arrestor inline between an antenna and a radio. If the radio works as well after installation as it did before then the arrestor is probably OK, assuming the gas tube isn't bad. After a lightning storm, if your radio stills works as well as it did before the storm then you know the gas tube is probably good. If you think the gas tube is probably bad then just replace it with a new one. jack Mark McElvy wrote: I have some Altelicon glass tube lightning surge arresters.

Re: [WISPA] Lightning Surge Suppressers
The way I test the surge suppressors I manufacture is to place a high voltage across the suppression device (such as your gas tube). The voltage must be higher than the breakdown voltage of the device. Frequently 120 VAC from the outlet will do. I use a variac coupled to a step up transformer so I can go to 1000 volts if needs be. You must put a current limiting resistor in series with the gas tube to keep from blowing a circuit breaker and damaging the gas tube. If the gas tube is firing, it will have a voltage across it at whatever level the breakdown voltage is. If it is not firing, the full applied voltage will be measured. If it is shorted, very low or no voltage will be seen. - Original Message - From: Mark McElvy [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Tuesday, May 20, 2008 1:15 PM Subject: [WISPA] Lightning Surge Suppressers I have some Altelicon glass tube lightning surge arresters.

Re: [WISPA] Lightning Surge Suppressers
Well the reason for concern is about a month ago I lost a 3 sector tower to lightning or at least during a lightning storm. Everything with an Ethernet port lost the Ethernet port as well as the three radios. I replaced all three aps but left the lightning suppressors in place. One of the AP's seems to have poor receive signals. I am trying to determine if it is the new foliage or a blown suppressor.

Re: [WISPA] Lightning Surge Suppressers
At $10 each its probably a lot easier and safer to just replace the tube when in doubt. A whole new arrestor is only $25!

Re: [WISPA] Lightning Surge Suppressers
I guess the question would changing the glass tube be a fix all or can the assembly go bad? Mark McElvy AccuBak Data Systems, Inc. WISPA Wants You!
