摘要： An arc fault demonstrator device for testing the efficacy of an arc fault interrupter (AFI) circuit breaker. The device includes a motor that moves a movable electrode relative to a stationary electrode under microprocessor control. A relay switches the electrodes connection between an arc voltage measurement circuit and an electrode close circuit. When current is applied to the electrodes, the measurement circuit provides voltage measurements to the microprocessor, which instructs the motor to move the electrodes closer or apart. When the arc voltage is below a low threshold, the electrodes are moved apart until the arc voltage exceeds a medium threshold. When the arc voltage exceeds a high threshold, the electrodes are moved closer until the arc voltage falls below the medium threshold. A switch switches between the AFI circuit breaker or a conventional circuit breaker to confirm that the AFI breaker will trip upon detection of the arc whereas the conventional breaker will not.

摘要： A portable circuit interrupter shutoff testing device and method, including a high current switch controlled by a timing circuit that allows current to flow through the switch and a small series resistance (in order to trip the instantaneous-trip function of the interrupter, as opposed to the overload-trip) for a short time period relative to the sine wave of the electrical power. A button activates the timing circuit which in turn activates the switch and current flows limited by the internal resistor of the device. By limiting the on time of the device to one or a few half cycles, the user can test if the circuit interrupter responds as quickly as specified by the manufacturer. A method includes receiving a stimulation indication, and selectively connecting an electrical load to wires connected to the circuit interrupter, wherein the electrical load is sufficient to trigger the instantaneous-trip function of the circuit-interrupter.

摘要： The invention relates to an apparatus and method for load testing electrical systems using a transformer having its primary windings connected to a power source and its secondary windings coupled to the device under test. The test apparatus may be used to test high power switching circuits to be implemented in three-phase power systems. One aspect of the invention involves eliminating the load resistor or load bank, which is normally used to simulate the working load when testing AC switching devices. In one embodiment, the load bank function is replaced by the secondary winding of a step-down transformer, and the voltage across the device under test is boosted using a second power source. In another embodiment, the primary current of the transformer is controlled to regulate the current in the device under test.

摘要： Test system and test method for testing the operability of test samples (7). A selection can be made in a user-specific manner from a plurality of test modules (2a-2c) which are made available, which can be assembled together to a desired test specification. A control module (1) carries out the overall test corresponding to the user-specific test specification, and controls individual selected test modules (2a-2c) in the desired sequence in correspondence to this test specification. Advantageously, there is produced automatically a test report on the test results of the individual selected test modules (2a-2c), which reports in particular embedded in the user-specific test specification.

摘要： The relay includes an input module capable of receiving 70 volt and 5 amp signals, respectively, from conventional instrument transformers, which are responsive to power line signals at their primaries. Output signals from the input module have specified, standardized levels suitable for electronic processing circuits, i.e. 1.4 volts and 0.1 volt. The output signals from the input module are applied through an accessible connector to a separate processing module which uses those signals in a conventional manner to determine possible faults on the power line. Low-level testing is accomplished by testing the outputs of the input module and by applying test signals simulating the standardized outputs of the input module to the processing module.
