Figure Different Applications of Partial Discharge Monitoring Systems
Item | Description |
GIS | Gas Insulated Switchgear (GIS) is the name for a unit that houses these components and circuits in a single gas tank with a compact footprint. Grounding devices that prevent electrical shock and lightning arresters that prevent dielectric breakdowns from lightning strikes are also included to enhance safety. During the operation of GIS equipment, partial discharge will occur due to various reasons such as its own material defects and external environmental influences. Partial discharge is an important parameter characterizing the insulation performance of GIS. It is a manifestation of its deterioration signs and an important cause of further insulation degradation and even failure. |
Transformers | A transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage. |
Power Cables | The power cable is an electrical cable that comprises one or more conductors held together with an overall sheath. The assembly is used for the transmission of electrical power either inside the ground or overhead or exposed. |
