INTRODUCTION What is a circuit breaker?A circuit breaker is an automatically-
operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
Fuse, which operates once and then has to be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.

What Is Mobile Agent Software ….?
Small software component that can perform functions on behalf of users.
Good software agent must able to adapt change in environment.
Share knowledge with other agent.

APPLICATION SCENARIOS Three Computers study Characteristics Of Data.The enterprise maintenance system may contain
the maintenance history database.Substation concentrator is in charge of collecting
data from the sensors installed on the circuit breakers.
Maintenance crew uses a mobile computer to access the information and prepares report utilizing software mobile agents.

16
Information Storage and Retrieval
Storing and retrieving all the information needed to perform maintenance or repair work.
Accessing the data saved into heterogeneous systems. Utilize some heuristic knowledge to do more complicated
search. Agent could use its own knowledge base to retrieve the
information. When the location or format of an information source is
changed, the central database will be updated or consult central agency.

Creating Circuit Breaker Failure Reports
Gather all the information and compile a report may be time consuming .
Failure report, the user needs to collect the circuit breaker information (manufacturer, type, voltage, etc) and operating environment data.
Software agent will create the report and send out additional mobile agents to the distributed information sources for collecting the data.
Generated report is in Extensible Markup Language (XML) format and contains only the necessary information about the failure report (e.g. HTML or PDF).

Circuit Breaker Monitoring Helpful in monitoring the status and events of circuit breakers. After monitoring starts, the selected events will be registered with the
mobile agent server running on the corresponding substation concentrator.
The concentrator can get the real-time information about breakers by communicating with sensors.
It can notify the user when the selected type of event happens.

20
Security Consideration The mobile agents need to be authenticated and authorized
at the servers. Data Integrity is highly essential. The mobile agent server can control agent's access to
resources depending on both the user identification and server permits.
Software provides options to encrypt the data when it is in transit and thus prevents others tampering with the data.

Logging and Experience Sharing
Software agents may help in logging and sharing maintenance experience.
The recorded experience can be saved in a case-based reasoning system for future retrieving.

Cost-Benefit AnalysisA cost-benefit analysis based on the risks
and investment return may be processed automatically.
A decision making sequence has been recommended, which consists of three stages. Some historical data will help the user to give a more appropriate score for assessing each failure mode.

Conclusions Suitable for application of maintenance practice
due to its support for heterogeneous systems, security, distributed events, low-bandwidth usage etc.
Using the mobile agent software, the development work can be greatly simplified.
Also, agent-based software architecture makes the application more flexible and upgradable.
