Product Description

 

Discharge detection Partial discharge detection Radio frequency signal detection Transformer discharge detection
 
 
 
PD signal detection RF module
 
 Partial discharge refers to the discharge that occurs between the electrodes but does not penetrate the electrodes. It is due to the weak current in the equipment insulation or defects caused during the production process. Repeated breakdown and extinguishment occur under the effect of high electric field strength. It manifests as the breakdown of the gas in the insulation, the local breakdown of the solid or liquid medium in a small range, or the concentration of the field strength at the edges and sharp corners of the metal surface to cause local breakdown discharge. The energy of this discharge is very small, so its short-term existence does not affect the insulation strength of electrical equipment. However, if the electrical equipment insulation continues to have partial discharges under operating voltage, these weak discharges will have a cumulative effect that will gradually deteriorate the dielectric properties of the insulation and cause local defects to expand, and eventually cause the entire insulation to breakdown.
