The Eaton Electrical Beaver High
Power Laboratory (Beaver Lab) is a high power testing
facility for the use of Eaton Electrical and outside
The Beaver lab is capable
of performing a wide range of electrical tests, some
examples are as follows:
overload, endurance, withstands, temperature rise, thermal
and magnetic calibration, vibration, and shock testing.
Typical test samples
include molded case circuit breakers, power breakers,
contactors, low voltage switch gear, bus duct, fuses, etc.
The laboratory is located 35 miles
north west of Pittsburgh in Beaver Pennsylvania, and only 17
miles from the Pittsburgh International Airport. A
dedicated 69,000 Volt power line supplies the power for the
lab. The Beaver Lab is organized into two sections:
the High Power Laboratory and the Low Power Laboratory.
High Power Lab
The High Power Laboratory uses a
three-phase transformer to feed the test circuits.
A series of reactors and
resistors is used in series with the transformer to provide
a wide range of voltage, currents and power factors.
The High Power Lab has
one test cell with a maximum capability of 600 Vac up to
100 kA (see
for complete details).
The control room is separated from the test cell by a cement
block wall. The wall has a series of windows, which allow
for full view of the test cell.
Low Power Lab
The low power lab has multiple
transformers which are dedicated to test cells which achieve
a wide range of voltages, currents and power factors.
There is one test cell dedicated to conducting current
interruption tests at a maximum of 600 Vac up to 10 kA.
Five other small cells are available for overload/endurance
testing up to 3000 A. The lab also has DC capabilities
of 250V up to 1500 Amps. In addition to the power
capabilities, the lab is also capable of performing other
types of testing: shock, vibration, low voltage
calibration (AC at various frequencies up to 400 hz and DC),
and thermal (at variable ambients).
Test reports are generated from
acquired data and given to the customer at the end of
testing. It is at the discretion of the customer whether or
not the lab maintains a copy of the test report. Test
results are kept confidential and are not disclosed to any
