Strange voltage system

[Hv&Lv]

Once the voltage on a motor gets high the magnetic portion of the motor will tend to go into saturation. This actually causes the motor to draw more current in order to magnetize the iron beyond the point where it is practical.

We go to many E&O conferences and discuss revenue streams and how to continue to reduce revenue losses. High voltage is one way to keep the revenue up.
As stated, resistance is a big part in the winter. Admittedly motors aren’t that big of a contributor but you have to remember this tiny bit is multiplied or divided by 50,000 depending on what your doing.

One big way to save is to get system losses to under 3%, another is to reduce the peak demand. Those are huge losses and affect bottom dollars

He may be looking at something that says it is rated for 125V and is thinking it needs that, then is extrapolating a 3 phase voltage from that (125x1.732). Usually that is just telling you the maximum voltage something can function with, not what you would actually feed it. For example if you look on the end of a NEMA 5-15 plug, it says “125V”. Sone people look at that and think it is the voltage that a device needs.

Interesting, I will confirm. Thanks.

Nope, that’s the regulator settings.
124 with 2v bandwidth Loaded and unloaded.

But where is that regulator located? Even If it's several miles away from a customer, I guess we can just assume the difference in voltage is negligible at different customer loading? What's probably more significant is the voltage drop through the transformer, probably three to four volts?

That’s a wrong assumption. Many people believe that.

Explain how low voltage will increase revenues?

The last paragraph is where CVR is important. Peak times only

When you use the word revenue here are you talking about revenue collected via the customer metering or are you talking about revenue lost because of inefficiencies in components ahead of a customer meter? Yes higher voltage on your distribution system is more likely to result in less line losses in places you won't be reimbursed for it in any way. If customer has line losses on his side of meter - that simply is lost kW and the meter will reflect it and you will be paid for energy delivered even if it wasn't used efficiently.
