What is the best way to operate
AdaptiVolt™, 24 hours a day or only certain parts of
the day or of the week?
Operating AdaptiVolt™ on a 24 hour per
day, 7 day per week basis provides the most benefit to both the customers and to
the utility. The only times we would recommend not operating AdaptiVolt™ to control
distribution delivery voltages at the lowest allowable level is during switching
operations that would disconnect end-of-line monitors and provide false voltage
information to the AdaptiVolt™ system.
Operating any less than full time
only reduces the energy savings that can be attained by the customers and the
utility. This amounts to about the same thing as leaving lights on when they are
not in use, a dripping water faucet or air leak in a factory compressed air
system.

Will the use of AdaptiVolt™ decrease the life span of
Load tap changers (LTCs) and step voltage regulators?
No, the implementation of AdaptiVolt™ will not significantly reduce the life of LTCs and voltage regulators.
Many manufactures of Load Tap
Changers offer contact life cycles of up to 500,000 operations before contact
replacement is required. (e.g.
Waukesha Transformers,
MR On-Load Tap-Changer VACUTAP® VV, and
ABB Transformers).
Over a forty year period, this would be equal to 34 tap changes per day.
Some voltage regulators have
contact rated lifetimes up to 2,000,000 changes (e.g.
GE Regulators,
GE VR-1 Single Phase Step Voltage Regulator).
This is equivalent to 136 tap changes a day for forty years.
The maximum number of tap change
operations induced by normal AdaptiVolt™ operation can be set by the utility. Normal
averages between 10-30 changes per day would be seen for optimum AdaptiVolt™ based
energy conservation and demand control.

What equipment will we need to add to the distribution system?
On typical applications, the only
equipment that needs added is the UtiliData® Line Voltage Monitor, to return
end-of-line voltages to the substation. The AdaptiVolt™ system interfaces with existing
regulators and load tap changers on the distribution line.
