Modular Wireless Test System for Electrical Inspections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multifunction electrical test systems are cumbersome for technicians, leading to inefficiencies and potential safety hazards due to heat generation and the need for repetitive testing of circuit breakers, which can cause distractions and increase the risk of errors during inspections.
Innovation Solution
A modular test system comprising dedicated hand-held devices for specific tests, such as RCD and loop impedance, that communicate wirelessly with a control device for result recording, allowing multiple technicians to perform tests simultaneously and separating physical testing from data recording to reduce heat-related issues and improve focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a technician uses a multifunction test device to perform multiple tests (insulation, ground, RCD, loop impedance), then all testing functions are integrated in one device, but the device becomes cumbersome and generates heat during repetitive testing
Solution Approach 1:
The patent divides the multifunction test device into separate specialized devices: an RCD test device, a loop impedance test device, and other dedicated testing instruments. Each device performs a specific testing function independently, eliminating the need for technicians to carry and operate a single cumbersome multifunction device while performing repetitive tests that generate heat.
2Productivity
If a technician repeatedly tests multiple circuit breakers using a multifunction device, then all breakers can be tested, but the repetitive nature causes distractions and increases error risk
Solution Approach 1:
The RCD test device and loop impedance test device are designed to be self-contained with automated testing capabilities. The devices perform tests autonomously without requiring the technician to manually switch between multiple functions or repeatedly connect/disconnect probes, thereby reducing distractions and minimizing human error while maintaining high productivity.
3Productivity
If multiple technicians perform tests simultaneously using separate devices, then testing speed increases, but coordination and data consolidation become more complex
Solution Approach 1:
The patent creates a universal testing system where multiple specialized devices (RCD test device, loop impedance test device) can operate simultaneously and independently. Each device is designed with standardized testing protocols and data formats that allow results to be consolidated without complex coordination, enabling multiple technicians to work in parallel while maintaining system simplicity.
Data Source
AI summary
An installation test system has a control device and one or more hand-held test devices. The control device and the one or more hand-held devices are in wireless communication via respective communication systems. The control device performs typical pre-power tests including insulation testing and ground testing. There is at least one hand-held device dedicated to testing for residual current in circuit breakers and another hand-held device dedicated to testing for loop impedance. The control device records all test data and stores data in storage.
