摘要： An apparatus (110) (FIG. 1) for differentially sensing a ground fault in a power distribution circuit is configured to route a plurality of power signals, the power signals when summed resulting in a zero sum signal. The apparatus (110) includes a circuit element (e.g., a resistor) (128), first and second current transformers (CTs) (112, 114, 116), and a routing circuit (118). The first and second current transformers (112, 114, 116) are configured to sense first and second power signals and to generate first and second sense signals representative of the first and second power signals, respectively. The routing circuit (118) is configured to receive the first and second sense signals to provide a residual signal across the circuit element (128).

摘要： An electrical fault detection device for use in a branch of a power circuit that utilizes signals from an AC line current sensor coupled to an electrical distribution line having a primary and neutral lines, a line high-frequency sensor coupled to the electrical distribution line, a differential current sensor coupled to the primary and neutral lines, and a ground fault current sensor coupled to the primary and neutral lines. A signal conditioner receives the signals outputted by AC current line current sensor, the line high frequency sensor, the differential current sensor and the ground fault current sensor and generates a signal indicative of the load current associated with a branch of the power circuit. Output of the signal conditioner is sampled and processed by a processing resource. The processing resource has stored therein data representing a plurality of time-versus-current curves that define a plurality of regions in which tripping may or may not occur. One region has time data and current data that define a time-duration for a particular current magnitude for which no tripping will occur. Another region has time data and current data that define a time-duration of a particular current magnitude for which tripping will occur. Processing resource processes sampled signal to determine the region to which the processed time data and current data correspond, and generates a signal to initiate tripping if the sampled signal yields a time duration for a particular current magnitude that corresponds to a region for which tripping must occur.

摘要： A circuit breaker system (100) providing a low impedance magnetic latch tripping scheme. The circuit breaker system (100) includes a trip unit (310) coupled to a switch unit (108). Trip unit (310) is coupled to an electrical circuitry and utilizes a current transformer (114) to sample a current conducting through the electrical circuitry. This current is processed into an input signal (126) suitable as an input to a trip circuitry (316) included in the trip unit (310). When a processor (322) senses an overcurrent condition in the input signal (126), processor (322) transmits a trip signal (128) to a switch (220) to initiate protection against the overcurrent condition, i.e., a trip of the electrical circuitry. Switch (220) permits a low release current to conduct through a low impedance electromechanical interface unit (218) such that the electromechanical interface unit (218) can actuate a mechanical opening mechanism included in the switch unit (108).

摘要： A system, method, and device for protecting an induction motor are disclosed. The exemplary system may have a module for determining the current drawn by the motor and a module for determining the state of the motor. The system may calculate a used thermal capacity based on a first formula when the motor is in an active state. The system also calculates the used thermal capacity based on a second formula when the motor is in an inactive state. When the used thermal capacity attains a threshold, the relay is tripped thus removing current to the motor and preventing motor from overheating. A method to derive thermal time constants from desired trip time limits (such as those defined by IEC standards or the thermal limit curves provided by motor manufacturers) is also presented. For example, the thermal time constants can then be used in tacking motor used thermal capacity throughout various motor states.
