As an update to the original problem I was losing power in the house circuits with no pattern that was traceable. The loss of power would affect one circuit and sometime later, weeks or months, power would be lost in another circuit. I would go to that circuit and inspect all the connections, boxes, switches etc. and I never found any thing wrong in that circuit.
Finally, I decided the house wiring was OK so the loss of power must be in the service drop between the CB box and the transformer. And so it was. After discussions with the local rural CO-OP power supply personnel a number of times they sent out a team that inspected the service drop from the transformer to the house. The culprit was in two of the bolted splice connectors. The connectors were about 32 years old and the tape had deteriorated permitting water to corrode the wire. With the corrosion, the conductors were loosened and the wind would make and break the contact under certain conditions. Some of the conductors had spark erosion when the arcing occurred.
All of the bolted splice connectors were replaced with a new a new design that should prevent this type of problem from reoccurring. The new connectors are a pressure type with silicon grease and crimped at about 2000 PSI. I think the design is such that water can’t get into the splice area.
I hope I have described the problem sufficiently to “get the word out” to the repair people so that they will remember to check the old bolt type connectors when there is an intermittent failure. With the hundreds and hundreds of old type connectors still in use this problem could be prevalent. Correcting this potential problem could save a lot of electricity. I say this because correcting this problem of increased resistance lowered my electrical bill from 895 KWH in March to 588 KWH in April. I can’t determine the exact savings because of the possible variables from one month to the next month but the savings were significant and continue to the present.
