East to West, same phase. Thank you, Bob

Can we feed a 1Ø pad mount transformer, from 2 different directions? It is the same phase both directions. Thank you, Bob

We use a bracket for both 3 phase and 1 phase. We are a Cooperative, so we make a circle ground or have 2 points were it is grounded. Thank you, Bob

Thank you, that answers my question. Bob

They are on utility poles, 5 sets per mile. Thank you, Bob

We are getting wrote up for hooking up lightning arresters wrong. The engineer wants the bottom to go to the pole ground. All 3 straight to pole ground. The old way was to hook 3 together, than take each one to the system neutral. What are your thoughts. Thank you, Bob

Thank you, that answered my question. Bob

We are upgrading a old service, OH to URD. New service is 2 phase 14.4 in a fiberglass transcloser. Primary URD is in 2 pipes,schedule 80 pvc. Transformers are on a concrete pad, 6" with rebar. Will we have trouble with eddy currents, because of the rebar in the concrete? Thank you, Bob

Thank you, waross. Bob

Temp. connection. 2 hot line clamps on #6 copper wire. One clamp on the floating high side, other clamp on the copper for the tank grounds. Thank you, Bob

Meterman and ape. changed a 480 volt meter at a water well. It is a 3 Ø 240/480 center grounded delta on the low side. High side is 14,400. Lineman grounded the high side before opening the cutouts. My question is when they closed the fuses in, they closed the 2 outside fuses in first. The...

Question was, why did the indicators not work. When they disconnected the regulator the OCR stayed in. That makes it a bad regulator. I did find out why they did not work.I will answer nice storys questions, no ,yes, we did not know the fault current at the time of the outage. After getting with...

We had a bad regulator on a primary line. Voltage is 7.2, the fault indicators did not work. The indicators are Linam 100 amp trip, made by Chance. The lineman put the indicators on both sides of the regulator, showed white. Disconnected regulator, tried the OCR, and it closed right in and held...

When I went back they had the transformers changed out. The transformers they took down, I could not find. On the dock, with other transformers. Thank you for all the help. Bob

Thanks for the help, I had to stay in today. Tomorrow I will go out and see what we can do. I will let you know. Bob

Would you explain in more detail? Thank you, Bob

3- 167 KVA transformers, they are hooked up wye-wye. 14.4 Ø to grd. This goes to a reda pump. They want 2500 volts Ø to Ø on the secondary. We have 2500 volts c to b, 1445 a to b,1445 a to c. 1445 Ø to grd. on a,b,and c. The 3 phases were all hot, polarity was the same. H2 was grounded. Anyone...

Update on the phasing of the 2 subs,substation guys switched the high side and low side. The 2 subs phase in now. I've another question, they switched another sub, the voltage 1200 volts, Ø to Ø on the 3 Ø. The sub people said it would be ok to heat this up, we did and it was ok. Is this not...

My background, I'm a superintendent for a REC in NW Oklahoma. We recently built a new 3 Ø line, 1/0 acsr. This is for a 2 way feed between the Fargo substation and the Gate substation. It would not phase in, 30 degrees angular displacement. Ø to Ø voltage is North Ø to North Ø 7200 volts, North...
