wire Exhibition 2024 Industry News - Partial Discharge Phenomenon and Electrical Equipment
Partial discharge is a phenomenon that occurs in high-voltage electrical devices, where discharge happens within an insulating medium under the influence of a high-intensity electric field without bridging the electrodes. wire Exhibition 2024 has learned that partial discharges can cause damage to the equipment and affect its normal operation.
Partial discharges typically exhibit three kinds of surface characteristics: light, heat, and gases. Therefore, by visual observation, temperature detection, and smell, the presence and severity of partial discharges can be detected and assessed. However, detecting partial discharges in electrical equipment remains a challenge.
To timely detect and address these issues, the power industry has introduced a partial discharge monitoring system. wire Exhibition 2024 understands that this monitoring system is a detection method conducted while the equipment is in normal operation, without needing a power shutdown. This is especially critical for devices with voltage levels between 10-35kV, where a large number, and a shutdown would directly impact the electricity users significantly. This method helps avoid inconvenience or financial losses due to power outages, thus enhancing the reliability of the utility companies' electricity supply.
Real-time monitoring allows for flexible scheduling of detection times based on the condition of the equipment, which is more conducive to timely discovery of potential problems. Compared to traditional testing methods, this approach is more direct and effective, enabling the timely detection of hidden dangers in the equipment and preemptively addressing possible faults.
In-service testing enables more timely detection and management of partial discharges, enhancing the reliability of the electricity provided by utility companies. It avoids the inconveniences or economic losses caused by power outages and also enhances the efficiency of the maintenance department, providing a robust guarantee for the stable operation of the power system.
