They've had it and are trying to kill Nessie?

yes it is how could you have guessed - they effed up bridge has long outstanding power quality issues soooo what do my engineers send me this time - these a$$hats with the resistance load and inductive load midway thru the cable to help with the capacitance issues the cable has

did it work ??? five whole volts at padmount at end of line snapshot of voltages where taken for thirty whole minutes ( i was a little pissed off at this)

the floatie contraption is four heating elements (they turned in the water where you cant see em)

Nola, could you explain this short bus style so i can understand/learn what's going on? Thanks

Frijoles!

So, if I follow you, they're using the water-heater elements on the floating SS Minnow there, submerged in the pond as a resistive load, and the motor as an inductive load, to try and cancel out what they think is high capacitance screwing up your power factor? I mean, it sounds smart, but what I see in the pictures looks stupid....

I don't pick up where the 5 volts fits in? Is that all you had at the end of the feeder once this contraption was turned on?

You are following correctly. The five volts was all we lost on the dead end. This capacitor effect is/has added as much as 2100 vac to the primary....so we think adding any load would help bleed off any voltage being added. Well one hundred amps worth of load managed to bleed off five volts one the secondary. We are not measuring the primary side.....prolly cause we really dont want to see how ugly those numbers are. An engineering firm is specing out a cap bank and getting numbers ready....this clown car $hit was to see if a temp fix could be attained.

Short bus, oh you mean our ride..... Transmission line is a concentric neutral single phase primary apx nine miles long. It has about four or five ground rods in that distance (speaking of dont try this at home). Google capacitance. Wiki will give you some really fancy formulas, use the one for round things. Use nine miles as your distance. Discuss with local poco engineer over beers and give him a good laugh. Tell him btw they only use nine amps athe dead end and intermittetly bounce that up to fiftey amps about once and hour for about four minutes. He should buy you a beer at this point for making him laugh so much. Then tell him the load is very sensitive electronic equipment. Then after he calms down tell him those guys put in all three phase equipment, but that transmission line is single phase. Offer him a napkin to dry his eyes cause he cant stop laughing. Ask him how stable the voltage should be.......

Nola, I know you've had VFD issues out there. Is it possible to ramp in your loads, or a similar load, slow enough that you wouldn't see the sudden charge?

Who's feeder is it? What about making it the POCO's problem: Drop in a HV line reactor?

Loads are ramped in slowly. 5hz 10hz and then i think l around 25 hz. Its for sure my feeder. POCO has all but told us to eff off . I dont know what a hv line reactor is. The photos were posted for amusement not for getting any answers. I know a lot of the commercial and resi guys never get to do any silliness like this.

It's the solution to your problems. The ones in that link are big guys, but you can get them in the kVA range.
