You might be able to take a small portable radio tuned to the hi end or low end of the AM dial and walk down the street if front of the 14 houses and see if the noise lever increases in front of one house. Even better is to check at the utility meters. Sounds like a nearby neighbor may have a...
Chances are the problem is in your house. If you have a battery powered portable radio, turn it on and see if you hear loud buzzing noise at the low end of the AM dial, then check the high end of the AM dial. Nothing? Carry the radio to various rooms and see if you can detect the LOUD BUZZING...
The transformer was probably manufactured in Mississippi. What you are hearing is a redneck fire alarm. They enclose a bag of popcorn inside the transformer, when it pops, the transformer is overheated.
The "Running Mode KVA Eq" looks like a good estimate of running load. Two of these equals 2 x 133 kva = 266 kva. All of the other misc load will run around 20 kva. A 300 kva 3-phase transformer would handle the running load, but I would chose a 500 kva transformer to handle the running load...
question 1 The plant's electric bill is based upon a charge for kwhr consumed during the month and a charge for peak monthly kva.
question 2 Dont worry about kvarh or amps, both are proportional to kva. The utility bills for kwhr and peak kva.
question 3 See the answer to question 2...
We have an old relay test set, RTS-150 made by EIL (now Ametek), it contains an add-on module which gives the test set 3-phase capability. But we don't have any instructions on how to use the module. Can anyone help us with wiring this module into the test of a 2.5 element transducer? Thanks
We have an old relay test set, RTS-150 made by EIL (now Ametek). Having trouble wiring up 2.5 element watt transducers to this test set so that it can be tested with single phase amps and volts. Can anyone tell us how to wire the 12 lugs? Thanks
Power companies are no longer run by engineers. Accountants, lawyers, and Women's Studies grads are now in charge. That explains why the Smart Grid is so exciting to everyone except those of us who still know what the hell is going on.
Call the power company. They probably have an industrial engineer or an ee who works with their industrial customers. He will be familiar with the electric rates. He can probably meet with you and give you some good ideas.
