TECHNICAL FIELD
[001] The present disclosure relates to protection devices for electric power distribution. More particularly, the present disclosure relates to a self-diagnosing electronic tripping device and method of operating the same.

BACKGROUND
[002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] Air Circuit Breaker (ACB) is an electrical device for providing protection to electric circuit again various faults such as over current and short-circuit current and voltage etc. The ACB is generally a combination of an electronic and mechanical device. Electronic trip unit is a part of the ACB that detect fault condition in a circuit and based on detection of the fault condition can break the circuit. Thus, providing the protection against overload, short circuit, ground fault and voltage-based protection.
[004] In the air circuit breaker, Microprocessor based electronics trip unit is incredibly complex, so the possibilities for something going wrong are extensive. Add to this the complexity and potential unreliability of hardware and system failure seems almost inevitable. If the electronics trip unit fails then, Air circuit breaker will not operate in fault condition, which may cause major damage to electrical system. Hence, self-diagnosis of the hardware and firmware of the electronics trip unit is necessary to ensure healthiness. The system, which will do self-diagnosis as well as recovery from any fault, is highly required in such type of application.
[005] Efforts have been made in the past to overcome problem associated with circuit breakers. For example, Japanese Paten Number JP 4511034 B2 provides An assembly comprising: a first ring assembly constructed and arranged to be rotatable about a first axis of rotation, said first ring assembly including an annular fluid container carrier portion having an inner periphery and an outer periphery between which said fluid container carrier portion is defined, said fluid container carrier portion being constructed and arranged to carry a plurality of fluid containers; and a second ring assembly constructed and arranged to be rotatable independent of said first ring assembly about a second axis of rotation that is generally parallel to said first axis of rotation, said second ring assembly being positioned with respect to said first ring assembly so that at least a portion of an outer perimeter of said second ring assembly is disposed radially inwardly of said inner periphery of said fluid container carrier portion of said first ring assembly, said second ring assembly being constructed and arranged to carry a plurality of pipette tips thereon. However, self-diagnosing electronic tripping device is Intelligent System which not only does self-diagnosis of peripherals but also run Auto Recovery to recover from the losses or faults. In case of non-recoverable loss, it will give alarm or notification to user whereas the patent JP 4511034 B2 is some mechanical system, which is not related to this patent.
[006] United States Patent Number US 8631283 B1 provides a monitoring and recovery of data instances, data stores, and other such components in a data environment can be performed automatically using a separate control environment. A monitoring component of the control plane can include a set of event processors for monitoring a workload of the data environment, where an event processor detecting a problem in the data plane can cause a recovery workflow to be generated in order to recover from the detected problem. The event processors can communicate with each other such that if one of the event processors becomes unavailable, the other event processors in a set are able to automatically redistribute responsibility for the workload. However, self-diagnosing electronic tripping device is an intelligent which not only does self-diagnosis of peripherals but also run Auto Recovery program to recover from the losses or faults. In case of non-recoverable loss, it will give alarm or notification to user whereas the patent US8631283B1 is data monitoring and recovery system.
[007] Chinese Patent Number CN 1711747 B discloses A portable communication device is provided that receives upgrade files via at least one wireless coupling. The contents of the upgrade file include information to repair errors in software components of the portable communication device and/or information to upgrade functions of the portable communication device. The portable communication device automatically upgrades the software components using the upgrade file contents. The portable communication device automatically recovers to an operational state when detecting an error or failure during the automatic upgrade. Further, the portable communication device resumes or reinitiates the automatic upgrade following the error or failure. However, self-diagnosing electronic tripping device is Intelligent System which not only does self-diagnosis of peripherals but also run Auto Recovery program to recover from the losses or faults. In case of non-recoverable loss it will give alarm or notification to user whereas the patent CN1711747B is to repair errors in software components of the portable communication device.
[008] United States Patent Number US 7397363 B2 discloses An apparatus including a first device which generates and/or transmits a first signal and which is associated with a web site and located remote from a premises or vehicle. The first signal is transmitted in response to a second signal transmitted from a second device located remote from the first device and remote from the premises or vehicle. The first device determines whether an action or an operation associated with the second signal is authorized or allowed and, if so, transmits the first signal to a third device located at the premises. The second signal is transmitted via the Internet and/or the World Wide Web. The third device generates and/or transmits a third signal for activating, de-activating, disabling, re-enabling, and/or controlling an operation of, a system, device, equipment, equipment system, component, and appliance, of the premises or vehicle. However, self-diagnosing electronic tripping device is Intelligent System which not only does self-diagnosis of peripherals but also run Auto Recovery program to recover from the losses or faults. In case of non-recoverable loss, it will give alarm or notification to user whereas the patent US7397363B2 is controlling an operation of, a system, device, equipment, equipment system, component, and appliance, of the premises or vehicle.
[009] United States Patent Number US 4377000 A discloses a multiprocessor computer control system for a process includes at least two central processors and respectively associated input/output systems. Control system faults are detected and a bootstrap microprocessor is triggered into its fault detector and recovery mode. The output control signals are placed on, central processors are stopped and restarted, and then it is determined which if any of them is to be inoperative. A reconfigured control system is defined with the inoperative unit(s) excluded. The microprocessor switches the input/output systems as necessary to structure the control system in reconfigured form so that process control can resume without disturbance. However, self-diagnosing electronic tripping device is Intelligent System which not only does self-diagnosis of peripherals but also run Auto Recovery program to recover from the losses or faults. In case of non-recoverable loss, it will give alarm or notification to user whereas the patent US4377000A is process control system.
[0010] There is therefore a need in the art to provide a self-diagnosing electronic trip device that self-diagnosis itself as well as hardware peripherals and embedded system. It will also give alarm and notification to the user in case of non-recoverable damage.

[0067] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other)and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0068] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C …. and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[0069] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
