SOLUTION FOCUS

The Fluke 3540 FC monitor provides real-time data capture.

in the Mojave Desert, where it can be cost prohibitive to
run conventional electrical lines. He has designed and
built portable and off-grid solar systems to operate well
pumps, power ranch homes, and illuminate street lights on
remote military bases, complete with battery or multigenerator backup systems.
Though he started NuEra in Arizona more than six
years ago, Dodds does the bulk of his business in California where the high cost of power helps makes solar
systems a legitimate option for commercial customers.
Add in energy savings through lighting, HVAC, and
other electrical upgrades and the cost savings become
substantial.
"One manufacturing-facility customer went from
paying what would be $23,000 per year at today's rates
for energy (their old rate was a bit less), to getting $90
in return from the utility less than two years later,"
Dodds stated.

Monitoring and documenting

Contractor, problem solver
Ken Dodds, the company owner and chief energy analyst,
has established himself over the years as an electronics
and electricity problem solver. He became a Californialicensed contractor in the 1970s. His early projects were
delivering power to remote ranches and other installations

MAY 2017

To efficiently document studies and identify such savings,
Dodds uses the Fluke 3540 FC three-phase power monitor
(Fluke Corp., Everett, WA, fluke.com) to track three-phase
systems at his client's plants. The monitor takes power
analysis and logging to a new level by putting the data
stream onto data servers. Dodds is then able to remotely
read and analyze these power measurements, depending
on the configuration:
■ current (A)
■ voltage (V)
■ frequency (Hz)
■ power (W)
■ apparent power (VA)
■ non-active power (var)
