Ultrasonic Porter High Frequency Partial Discharge Monitoring Device

At present, metal enclosed switchgear is widely used in power systems, so the stability and reliability of switchgear operation are of paramount importance. Defects such as bubble gaps, impurities, spikes, etc. inside the insulation of medium voltage electrical equipment, under the action of strong electric fields, cause uneven distribution of electric fields inside the insulation of the switchgear. The electric field strength at the defect site will increase, which can easily lead to partial discharge that does not penetrate the entire insulation at that location. Partial discharge generally does not cause penetrative breakdown of the insulation inside the switchgear, but it can lead to local damage to the insulation medium. If it exists for a long time, it will cause damage to the electrical strength of the insulation device under certain conditions, ultimately leading to insulation breakdown inside the switchgear. For electrical equipment, partial discharge is one of the important causes of insulation aging, deterioration, and even damage, leading to equipment damage and power system accidents. It is also a sign of equipment insulation integrity degradation. Therefore, monitoring and detecting partial discharge of electrical equipment is an important means to evaluate the insulation condition of the equipment, and it is also an effective measure to detect latent faults in the equipment, achieve fault warning, and avoid the occurrence of faults. APD seriesUltrasonic Porter High Frequency Partial Discharge Monitoring DeviceThe partial discharge monitoring device for medium voltage switchgear monitors and detects the partial discharge signals of electrical equipment during operation through ultra-high frequency sensors (UHF), ground electric wave sensors (TEV), and ultrasonic sensors (AE), in order to determine whether there are insulation hazards inside high-voltage electrical equipment, issue early warnings, and ensure the safe and reliable operation of the power system.
