Multi-tap Transformers for Electric
Submersible Pump (ESP) Applications
Ultimate flexibility with safer, more
reliable multi-tap transformers
Increase reliability and
flexibility in the field by
using Eaton's Cooper
Power Systems
multi-tap tansformers
for Electric Submersible
Pump (ESP)
applications.
System challenge
Electric Submersible Pumps
(ESP) used in artificial lift
operations for oil production are
commonly located anywhere
from 2,000 to 20,000 feet
below ground. Cable is fed
down a hole to provide power
to these pumps. Voltage drop
over this length of cable can be
several hundred volts, beckoning
the need for quick and easily
adjustable voltage feeding the
pump.
Eaton’s Cooper Power Systems
multi-tap transformers are
designed to meet this very
need.
Solution
Our multi-tap transformers
step-up the low voltage output
from a Variable Speed Drive
(VSD) to power your ESP. With an
input voltage of 480 V and output
voltages ranging from 750 Delta
to 4850 Wye, our transformers
can meet a wide variety of pump
applications. We utilize 25
different voltage settings, which
are easily adjusted via the two
de-energized tap changers on the
transformer.
Eaton's Cooper Power Systems
provides the solution in two
ways:
•
Standard designs available
with shorter lead-times
•
Engineered to order designs
provide the flexibility to mate
up with any drive and pump/
motor combination.
Increased safety and reliability
•
Multiple taps provide system
tuning for factors including:
•
Application flexibility at
multiple depths
•
Fluid volume and pressure
•
Changes in pump conditions
•
Gauges and drain valve with
sampler provide easy system
health and diagnostics
•
Cover-mounted pressure relief
device provides additional
safety where needed
•
Save thousands of dollars
on costly third-party field
certification with our
factory UL® listed multi-tap
transformers
•
Short-circuit testing per IEEE
Std C57.12.90™-2010 standard
Multi-tap transformer cable
compartment with door open.
Eaton’s Cooper Power
Systems multi-tap
transformers utilize the
same proven methods
as our conventional
three-phase distribution
transformers, ensuring
the same level of
quality that you’ve
come to expect.
Environmentally preferred
construction
Eaton's Cooper Power Systems
transformers are the industry’s
first multi-tap transformers
available with Envirotemp™
FR3™ fluid, a vegetable oilbased, high-fire-point dielectric
coolant. These transformers
offer an environmentally
responsible, high efficiency,
safer choice.
