 Another center pivot call yesterday. I truly love going out to the hay fields and helping the hay farmers. Big vistas, and cool machines! Got this one going fairly quickly. Just a plugged up end gun nozzle. That's it you see spaying in the center of the photo. The 'ole boys cooked steaks and potatoes and insisted I stay and eat, before they'd let me leave!

 Had a call to a home that the owners felt they were being over charged for power. They were seeing bills of over $200.00 a moth for a small home with little electrical usage. Water heater is gas, furnace is gas. I checked the actual 240 feeder lines amp draw and calculated the wattage and Kwh (kilo watt hour) usage. I estimated they would see around $96.00 dollars a month based on this reading.
I Kwh = 1000 watts for 1 hour. I have inserted the method for calculating your own wattage from your meter using the formula shown. It's simple math, so don't get nervous. Follow the directions shown and you can figure out what you are using for the whole house, if you're interested. You will need your residential rates from your utility. Most have them posted on line. Ours here with La Plata electric is 11.3 cents/Kwh. So you multiply your watts product from the formula by .113. Pretty easy! The example here is 5400 watts. Remember to calculate the number of hours at that sustained rate too. It's a bit tricky to know how the usage is changing, based on what's being used, and for how long. That's the key to getting an accurate number. |
