POWER LINE TESTING DEVICE WITH SIGNAL GENERATOR AND SIGNAL DETECTOR

摘要

A power line testing device with signal generator and signal detector incorporates a DC power supply that is capable of generating DC power from a miswired outlet, as long as there is a hot conductor and a return path. The device includes a signal generator which generates a signal that is easily distinguishable from noise. The transmitter further includes a spark gap for creating an arc used to test the function of an ACFI device connected to the branch under test. The transmitter further detects the integrity of circuit ground by measuring its impedance. A receiver of the device measures the elapsed time of the testing signals, permitting a more sophisticated test of interrupter device function.
