Hello community, first time posting long time viewer. I have been in search of assistance to settle a debate. I'm hoping you may assist me in coming to a resolution. The problem lies on a city block, 25kva transformer feeding 8 homes. The transformer is pole mounted and at that point it feeds 2 houses on each side of it for a total of 4 at that pole. The other 4 homes, it goes aprox 100' 1/0triplex, then feeds 2 homes. Goes across the road aprox 40' and feeds the last 2. The last 2 and one of the ones before it goes across the road are experiencing dim lights and then flickering lights. All connections have been changes and the issue persists. Voltage at one of the homes at the end is 115 and 113 with 22 and 26 amps. This is also similar to their neighbor and to the homes across the road. The homes fed directly from the transformer have 118 and 119 and use 18 and 20 amps. The transformer has 90 and 86 amps at a non peak hours. Applying a "load beast" you're able to raise the amp over the transformers full amp rating of 104amps simulating the dim lights/flickering lights. Now that you're caught up to the current situation, what may be the correct course of action to resolve this issue. 1 idea is to upgrade the transformer. Another suggested on the last 4 homes, place the connections from the 2 homes across the road in front of the connections to the other homes. (I personally don't believe this is the resolution, but I need proof via circuit drawings or other means to prove this isn't the solution. Circuits in series "see" all amps and distribute voltage accordingly. So amperage is the constant in a series circuit.) Lastly to finish and clean up the question. Will moving connectors in front of other connectors improve voltage and cure the dimming/flickering lights, or will upgrading the transformer be the best resolution?
