Load Fault Isolation Using Power Data in Electrical Circuits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional circuit breaker systems face challenges in identifying fault causes as faults can occur anywhere downstream, requiring manual iterative testing of loads and connections, which is inefficient.
Innovation Solution
An electrical power system with a load fault module that uses load information and power data to determine faulty loads by successively shutting down or turning on controllable loads while maintaining power, and employing machine learning to diagnose faults, with the option to output instructions to a user interface for manual control.

Engineering Contradiction Analysis
1Productivity
If manual iterative testing of loads and connections is used to find faults, then the fault identification process can be completed, but the process is inefficient and time-consuming
Solution Approach 1:
The system enables automatic fault identification through the load fault module that autonomously determines faulty loads by analyzing load information and power data, eliminating the need for manual iterative testing and significantly improving fault identification efficiency
Solution Approach 2:
The patent replaces manual mechanical testing processes with automated electronic analysis. The load fault module uses electronic data processing and machine learning algorithms to identify faults, substituting the manual physical testing approach with an automated computational system
2Measurement precision
If all loads are tested to identify the faulty one, then accurate fault identification can be achieved, but the complexity of the process increases
Solution Approach 1:
The load fault module extracts and analyzes specific load information and power data from the electrical circuit to identify faulty loads. By focusing on relevant data parameters rather than testing all loads comprehensively, the system achieves accurate fault identification while reducing process complexity
Solution Approach 2:
The load fault module acts as an intermediary between the circuit breaker and the loads. It receives fault indications from the circuit breaker and automatically determines the faulty load by analyzing power data, serving as an automated mediator that simplifies the fault identification process while maintaining high accuracy
3Extent of automation
If conventional circuit breaker systems are used, then the system structure remains simple, but the ability to automatically identify faults is lost
Solution Approach 1:
The load fault module integrates multiple functions into a single device: it receives fault indications from the circuit breaker, analyzes load information and power data, determines faulty loads, and provides control signals. This multi-functionality enables automatic fault identification while consolidating system complexity into a dedicated module
