Beaver High Power Lab

The Eaton Electrical Beaver High Power Laboratory (Beaver Lab) is a high power testing facility for the use of Eaton Electrical and outside clients.

The Beaver lab is capable of performing a wide range of electrical tests, including: current interruption, 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 capabilities 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

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 other parties.
