Partial discharge can accelerate the damage to the insulation of power equipment, reduce the life of insulation, and seriously affect the safe operation of equipment
[0003] At present, the detection of partial discharge of XLPE power cables still relies on the visual method for partial discharge and combined with existing experience to carry out partial discharge mode. This method has a certain degree of subjectivity, lacks scientificity and accuracy, and is low in efficiency. Therefore, We need a more efficient method to achieve partial discharge mode in XLPE power cables

Description
technical field [0001] The invention relates to the field of power equipment testing, in particular to an XLPE power cable partial discharge testing system. Background technique [0002] With the advancement of society, the power system is also developing rapidly. The voltage level of the power grid is getting higher and higher, and the coverage area is getting wider and wider. The safe and reliable operation of power equipment is becoming more and more important. Since power equipment is generally located outdoors, it is inevitable The ground will cause insulation damage, aging and other phenomena, and partial discharge will also occur accordingly. Partial discharge can accelerate the damage to the insulation of power equipment, reduce the life of insulation, and seriously affect the safe operation of equipment. [0003] At present, the partial discharge detection of XLPE power cables still relies on the visual method for partial discharge and combined with existing experi...
