Due to their lack of response

CEMC

May have caused damage to your property?
If you are on the Cross Plains Tennessee substation you need to be advised, that if you had any electrical equipment, IE, appliances, heating or air conditioning or other items that contain voltage sensitive components ( computer, dvd/vhs recorder/ players, televisions ), CEMC has insurance that should repair or replace the damaged item or equipment due to their lack of response for replacing their failing equipment.

They will try to tell you that they have no way of knowing, but this is not true. These folks have complete monitoring of what is going on with the substation via remote monitoring and chose to ignore the warning signs.

You know it isn't rocket science, " Nothing lasts forever. " You know if you don't change the oil in your vehicle things break faster and you get to either buy a new engine or junk the vehicle.



You know they Drag Down From Us Customers Over $2,000,000.00 a month for mainteance of Wires, Poles, Equipment, and Facilities. You ask me in my opinion it is all the new vehicles they're riding around in, is what they are wasting the money on, and not the equipment we need replaced to prevent the damage to our property. I was told years ago they have a " Wait until it breaks policy " which appears to be the case. And we are the ones that spend the money to replace these items in our homes or businesses.

Another interesting comment from Howard Whitaker was and I quote" That is what insurance is for. " I really wonder who's insurance he was refering to , ours or theirs. I can tell you too many times on ours, and they drop the insurance policy and you play HELL finding a new one with the same policy coverage at the same money cost.

For the last 2 years the wife and I have had special equipment installed that monitors the condition of the incoming power to our home. This equipment has several conditions that it records and maintains a log of the incoming power to our home.

I had disclosed this information to Howard Whitaker the Area 2 manager in April of 2012 nothing was done until a power outage in October of the same year. It was in July of 2012 we were hit with 3 spikes that month that were for sure in excess of 130 volts AC.

And now already in this new year we have had another spike in January 2013. So they have either not repaired the first problem or something else is breaking down.


This equipment was state inspector certified as installed correctly.

Fault ImageExplanation of Fault Code
Fault 26 is when the AC line frequency of 60 cycles per second drops below the set parameter limit of the monitoring device. In this case it was 55 cycles a second.

Under frequency is really bad on compressors in air conditioning systems and refrigerators.
Fault 29 is when CEMC has a problem with their equipment,it may be the primary of the transformer shorting to the secondary or poor switching or whatever that induces the supply line ( Over head wires in your front or back yard ) to your home to raise the supply voltage and then the transformer passes it along to your electrical equipment, but what ever it is when the AC line voltage exceeds the set default parameter of the monitoring device. In this case it was 130 Volts AC.

Most electronic equipment nowadays has what is called a switching power supply in them. In short the 120 Volt AC is converted to DC to run most electronic devices its regulator takes the 120 volt DC input and drops it down to 12 volts or less in most cases, but computers are very sensitive because they use very low voltages and the microprocessors in them won't survive the spikes. Almost every device nowadays has some sort of low to medium level microprocessor in it to make it operate or preforms a specific duty.

When the regulater goes out the full force of the 120 DC is there and usually cases damage that is NOT repairable. Computers, TV's, and almost every electronic device nowadays use 12VDC or less for there operatrion. Even nowadays your home heating and cooling systems are getting away from power supplies that have a transformer in them to these switching power supplies. The DOWN side to these supplies are they don't usually survive the power spike that the utility company is capable of hitting you with.

Power supplies with transformers in them will handle the Spikes better but still can fail and allow the spike to pass to the device it is connected to.
Fault 39 is when there is a power outage or when the lights just flash on and off or when the line voltage drops below the monitoring devices defined limit of 106 volts AC in this case.

This could have been a branch swinging back and forth shorting out two wires or any number of causes. But when it turns off and comes right back on in a second or less this causes a surge that damages equipment.



Below you will see images of the display of the monitoring device, and yes there are several duplicates of dates. I was having a hard time seeing the camera display to take the picture and it was a good thing I did because of the images are at times pretty blury and can be seen better in others .

So if you have had a device fail and have a reciept of replacement make them pay for it. Here is your proof and best of luck in your recovery.
