Test of electrical resistance connection between Power brush and Soft Cable
Introduction
The connection between the power brush and the soft cable plays an important role in electric system, which is an essential parts - the conductive path between the devices in an electrical system. The electrical connection between the power brush and the soft cable is the basis of forming reliable electric contact- one of the most important safety requirements of electrical system. In this project, the electrical resistance of the power brush/soft cable connection is going to be tested and discussed. This test will then allow electrical engineers to determine the performance of the power brush/soft cable connection, analyse present operation conditions and taking preventive and corrective action.
Test Setup
The test setup for this project is relatively simple. The equipment needed for the test is two power brushes and two soft cables, each connected to the test equipment in opposite direction. A low resistance ohmmeter, preferably a multi-function meter and power source (DC, AC, or other current) will also be needed.
The connection of the power brush/soft cable will remain in place throughout the test. During the test, measurements will be taken of the current, voltage and resistance between the two power brushes, and between the two soft cables. Each of the four points will be manually measured and recorded in a spreadsheet.
Test Methodology
The first step of the test is to ensure that both power brushes and soft cables are correctly connected. After checking the connections, the test will be started by measuring the following parameters:
Current: This is a measure of the amount of current running between the two brushes. Ideally, the current should be at a stable level throughout the test.
Voltage: This provides a measure of the amount of voltage at the connection point between the two brushes and the two cables. Ideally, the voltage should remain constant during the test.
Resistance: This provides a measure of the electrical resistance between the two brushes, and between the two cables. Both should remain relatively constant during the test.
The data collected during the test will then be analysed to calculate the electrical resistance of the connection between the power brush and the soft cable.
Results
The results from the test showed that the electrical resistance of the connection between the power brush and the soft cable was very low. The current, voltage and resistance readings were consistent throughout the test and remained within the expected range.
Conclusion
The results of this test showed that the electrical resistance of the connection between the power brush and the soft cable is very low. This indicates that the connection between the two components is reliable and form a good electrical contact. This results will help electrical engineers to determine the performance of the power brush/soft cable connection, analyse present operation conditions and taking preventive and corrective action.
