摘要： A monitor/analyzer for an ac electrical system can be programmed through a display on the front panel to respond to selected events by generating triggers signals when selected monitored electrical parameters including neutral current exceed programmed thresholds. The trigger signals initiate simultaneous waveform capture of multiple waveforms in the ac system. Multiple trigger signals result in sequential waveform capture so that if a plurality of triggers are programmed for the same event, extended waveform data is captured for the event. Alarm screens are generated in response to the events, as well as for hardware failure, an excessive neutral-to-ground voltage or reverse sequence.

摘要： A digital monitor/analyzer for an ac electrical power system samples the current and voltage waveforms at a slow rate for performing metering functions, and at a high rate for analyzing harmonic content. Sampling is performed in sampling frames comprising a plurality of repetitions of sampling for a selected number of cycles followed by a delay of a fraction of a cycle. This effects equivalent sampling at a higher rate for slow speed sampling over a frame. High speed sampling is performed over only one repetition of the selected number of cycles in a frame so that it can be carried out sychronously as required for the harmonic analysis. The high speed sampling rate is an integer multiple of the slow speed rate so that slow speed data can be extracted from the high speed samples for continuous metering. Fourier analysis of the harmonic content of the waveforms is performed on the odd interrupts while all of the other tasks are apportioned out over the even interrupts of a sampling frame. Both the odd and even interrupts initiate sampling.

摘要： False ac signals produced by a noise suppression capacitor across a switch applying a switched ac line voltage signal to a logic input of a microprocessor in an electrical apparatus such as, for example, a contactor or circuit breaker, are phase shifted with respect to a true ac input by inserting two series resistors, and a diode shunting one resistor, between the switch and the logic input. This creates a larger window in which to discriminate between the zero crossings of the true and false ac signals.

摘要： Apparatus for measuring current over a wide range generates an eight bit accurate, 16-bit dynamic range digital signal from a current transformer secondary. Two signals proportional to the rectified secondary current, one generated by a large burden resistor and the other by an amplifier with programmable gain and an overrange indication, are applied through a multiplexer to an eight bit analog to digital converter which has three selectable reference voltages. A microprocessor selects the input signal, converter reference voltage, and one of four levels of amplifier gain which provide the greatest resolution for the magnitude of the current being measured, and provides an appropriate scale factor, from 2.sup.0 to 2.sup.8, for the eight bit accurate digital signal generated by the analog to digital converter.

摘要： A solid-state load protection system whereby a poly-phase alternating current system is monitored enabling a loss of phase feature to be used. A current sensing function is utilized so as to produce an output signal which is related to the current in an electrical circuit. Attached to the current sensing function are two capacitors each having their own signal path so as to have different charging and discharging rates. During a loss of phase condition, one capacitor discharges more quickly than the remaining capacitor with the result that the voltage across the quickly discharging capacitor, which during normal conditions is greater than the remaining capacitor, now becomes less than the remaining capacitor. A loss of phase sensing function detects this difference in potential levels thereby initiating a trip signal to the output function. The output function upon receiving a trip signal causes a light-emitting diode to conduct and also deenergizes a contactor through which a current source is connected to the load.

摘要： A first input signal representative of the voltage component is integrated producing an integral signal. The integral signal is compared to fixed reference potentials. A second input signal representative of the current component is sampled when the instantaneous magnitude of the integral signal equals a reference potential. The sample value is digitized and the integrator is reset by variable width reset pulses. Successive sample values are accumulated producing totalized values representative of the time integral of the product of the current component and the time integral of the voltage component, or energy.

A main winding is carried on a leg of the E-conformed member to provide two closed magnetic paths. A control winding is wrapped about another of the legs and encircles only one of the closed magnetic paths. A bilateral switch connects to the control winding and is actuated by a signal-generating means which is responsive to a lamp operating condition to close the bilateral switch once each half cycle of energizing potential during normal lamp operation, with the resulting counter mmf decreasing the inductance of the ballast apparatus by a predetermined amount to control in a very accurate, simple and inexpensive fashion the average power delivered to the lamp.

摘要： Outdoor lighting fixture utilizes lamp ballast which includes both solid-state control circuitry and a relatively massive inductor ballast. The solid-state control circuitry is mounted in a separate housing, such as the photocontrol housing, which is affixed to the exterior of the fixture by means of a plug-type receptacle, and the relatively massive inductor portion of the ballast is contained within the fixture body. Those portions of the solid-state control circuitry which require cooling use the separate housing as a heat sink. If troubles are encountered in the solid-state circuitry, the entire circuit can be replaced simply by plugging in a new unit.

摘要： A circuit interrupter includes first, second and third electrical conductors, a planar conductive member having first, second and third contacts, and an operating mechanism structured to move the planar conductive member toward the electrical conductors to electrically connect the first, second and third electrical conductors to the respective first, second and third contacts, and to move the planar conductive member away from the electrical conductors to electrically disconnect the electrical conductors from the contacts upon the occurrence of a predetermined condition, such that the electrical conductors are electrically isolated from each other. When one of the electrical conductors is welded to one of the contacts, the operating mechanism and the planar conductive member cooperate to electrically disconnect the other two of the electrical conductors from the other two of the contacts upon the occurrence of the predetermined condition.
