APD Series Partial Discharge Monitor

Partial discharge generally does not cause penetrating 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. Therefore, for electrical equipment, the occurrence of partial discharge is one of the important reasons for insulation aging, deterioration, and even damage, leading to equipment damage and power system accidents. At the same time, partial discharge 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 status of equipment, and is also one of the effective measures to detect potential faults in equipment, ultimately achieve fault warning, and avoid the occurrence of faults.
