What are the best practices for testing technology in high-electric field environments?

由人工智能和领英社区提供技术支持

Testing technology in high-electric field environments can be challenging, risky, and expensive. High-electric field environments can cause breakdowns, sparks, arcs, and corona discharges that can damage or destroy the technology or the testing equipment. Therefore, it is essential to follow some best practices to ensure the safety, reliability, and validity of the testing process. In this article, you will learn about six best practices for testing technology in high-electric field environments, such as choosing the right test site, shielding the technology, controlling the voltage, monitoring the temperature, recording the data, and analyzing the results.

1 Choose the right test site

The first step to test technology in high-electric field environments is to choose a suitable test site that can provide the desired electric field intensity and configuration. Depending on the type and purpose of the technology, you may need to test it in a laboratory, a field station, or a real-world scenario. For example, if you are testing a lightning protection system, you may need to use a high-voltage generator or a rocket-triggered lightning facility. If you are testing a power transmission line, you may need to use a live or simulated network. You should also consider the environmental factors, such as humidity, wind, and noise, that can affect the electric field and the testing results.

Testing technology in high-electric field environments requires careful planning and adherence to best practices. Use shielded cables and components to minimize electromagnetic interference, conduct thorough pre-testing simulations, and implement robust grounding techniques. Regularly calibrate equipment, employ surge protection devices, and perform continuous monitoring during testing. Additionally, document all procedures and results meticulously to facilitate analysis and future improvements. Regularly review and update testing protocols to adapt to evolving technologies and environmental conditions.

2 Shield the technology

The second step to test technology in high-electric field environments is to shield the technology from unwanted electric fields and electromagnetic interference. Shielding can prevent or reduce the effects of breakdowns, sparks, arcs, and corona discharges that can damage or destroy the technology or the testing equipment. Shielding can be done by using metal enclosures, screens, cages, or coatings that can block or divert the electric fields. You should also use appropriate grounding, insulation, and surge protection devices to protect the technology and the testing equipment from electrical hazards.

Proper grounding is absolutely critical for safety and accuracy reason. ESD (Electro Static Discharge) can cause damage to electronics components such as solid state semiconductor chips (CPU, Memory, Storage). EMI (Electro Magnetic Interference) on the other end will affect the test result and cause data inaccuracy. Grounding will help to reduce risk of electric interference in the test environment and safety risk of electrocution to workers, engineers and staffs.

3 Control the voltage

The third step to test technology in high-electric field environments is to control the voltage applied to the technology or the testing equipment. Voltage is the main factor that determines the electric field intensity and the likelihood of breakdowns, sparks, arcs, and corona discharges. Therefore, you should use a reliable and precise voltage source that can provide the required voltage level and waveform. You should also use a variable voltage transformer or a rheostat to adjust the voltage gradually and avoid sudden changes that can cause surges or spikes. You should also monitor the voltage continuously and stop the testing if the voltage exceeds the safe or desired range.

4 Monitor the temperature

The fourth step to test technology in high-electric field environments is to monitor the temperature of the technology and the testing equipment. Temperature is another factor that affects the electric field and the performance of the technology. High temperature can increase the conductivity and reduce the resistance of the materials, which can lead to more breakdowns, sparks, arcs, and corona discharges. Low temperature can decrease the flexibility and increase the brittleness of the materials, which can lead to cracks or fractures. Therefore, you should use thermometers, thermocouples, or infrared cameras to measure the temperature of the technology and the testing equipment. You should also use fans, heaters, or coolers to regulate the temperature and keep it within the optimal or specified range.

A very important thing to consider before getting your electric instruments on the electrified cables is a heat test with the use of an infrared or heat camera, to anticipate specific risks of electric arc in those points of failure. That specific heat, more of the times is related to bad connections or coupling.

5 Record the data

The fifth step to test technology in high-electric field environments is to record the data generated by the testing process. Data can include the voltage, current, power, electric field, temperature, breakdowns, sparks, arcs, corona discharges, and other relevant parameters or events. Data can provide valuable information and feedback about the performance, behavior, and response of the technology in high-electric field environments. Therefore, you should use sensors, meters, oscilloscopes, cameras, or other devices to capture and store the data. You should also use data loggers, computers, or software to organize and label the data.

6 Analyze the results

The sixth and final step to test technology in high-electric field environments is to analyze the results obtained from the data. Analysis can help you evaluate the effectiveness, efficiency, and reliability of the technology in high-electric field environments. Analysis can also help you identify the strengths, weaknesses, opportunities, and threats of the technology in high-electric field environments. Therefore, you should use statistical, graphical, or numerical methods to process and interpret the data. You should also use benchmarks, standards, or criteria to compare and contrast the results with the expected or desired outcomes.
