Special test equipment was designed and fabricated at the National Aviation Facilities Experimental Center (NAFEC) to create controlled power interruptions to Federal Aviation Administration (FAA) electronic equipment. The test equipment, designated Power Interrupt Equipment (PIE), interrupts and restores power at precise phase angles. This capability enables specific types and periods of outage to be caused so that outage effects on the unit or system under test can be analyzed. Maximum inrush current can also be produced so that its effect on circuit breakers and the operation of the unit or system under test can be analyzed. PIE was found capable of satisfying the requirements for interrupting and restoring power at precise phase angles. This test equipment facilitates test and evaluation of FAA equipment with respect to the capability of handling power interruptions.
