Solution Overview
Problem
Current systems lack the ability to effectively detect and mitigate high-speed transient events in electrical systems, leading to equipment failure, production downtime, and revenue losses due to the difficulty in identifying transient sources and their characteristics.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple monitoring devices are deployed to detect transient events, then measurement precision and location identification improve, but device complexity and cost increase
Solution Approach 1:
The system divides the electrical power system into multiple monitoring zones, each equipped with its own monitoring device. Each device independently detects transient events at its location, and the controller aggregates data from multiple segments to determine overall transient characteristics and location, thereby improving measurement precision through distributed sensing.
Solution Approach 2:
A controller acts as an intermediary that receives transient event data from multiple monitoring devices, processes the information, and determines transient location and characteristics. This intermediary consolidates the complexity of managing multiple devices into a single coordination point, improving measurement precision while managing system complexity centrally.
2Reliability
If comprehensive transient characteristics data are collected, then troubleshooting effectiveness improves, but loss of time for analysis increases
Solution Approach 1:
The system pre-configures the controller with the capability to automatically analyze transient characteristics data as it is collected. Rather than waiting for complete data accumulation before starting analysis, the controller performs preliminary processing and pattern recognition in real-time, reducing the total time required for troubleshooting while maintaining comprehensive data collection for reliability.
Solution Approach 2:
The controller continuously monitors incoming transient data and provides real-time feedback on detected patterns and anomalies. This feedback mechanism enables ongoing analysis that identifies troubleshooting opportunities as they arise, reducing overall analysis time while maintaining comprehensive data collection for accurate reliability assessment.
3Productivity
If automated transient evaluation is implemented, then productivity and response time improve, but device complexity increases
Solution Approach 1:
The controller is designed as a multi-functional device that performs multiple tasks: collecting data from monitoring devices, analyzing transient characteristics, determining location, and generating troubleshooting recommendations. By consolidating these functions into a single universal controller, the system achieves high productivity through automation while managing complexity through functional integration rather than proliferation of specialized devices.
Data Source
AI summary
A system and method to evaluate characteristics of transient events in an electrical power system to determine the location of a transient source type, the source type of a transient event, and suggested mitigation measures that might reduce or eliminate the effects of the transient. The electrical power system has a plurality of monitoring devices that each may detect the occurrence of a transient event incident upon the power system. A controller is coupled to the monitoring devices. The monitoring devices measure signal parameter values associated with the transient event, and the location of the transient event is automatically determined by evaluating transient characteristics from each of the recording monitoring devices. Other measurements of signal parameters may be made to determine transient characteristics. The transient characteristics may be used to determine the source of the transient event, the type of transient event, mitigation measures, and the effects or predictive effects of mitigation measures.
