Online Partial Discharge Monitoring of Power Transformers
Dielectric flashover of transformer bushing and winding insulation is one of the most frequent causes of failure in power transformers. Insulation degradation in bushings and windings is influenced by various electrical, thermal, mechanical and environmental stress factors over many years in service.
Partial discharge (PD) activity is an indication of weak spots in the insulation that can cause failure and damage to power transformers and can be continuously monitored over a specified period of time to trend PD activity over time to efficiently plan further diagnosis as well as maintenance to prevent failure.
MONTESTO 200 is a portable, two-in-one solution that enables you to perform both temporary on-line partial discharge (PD) monitoring and on-line PD measurements on power transformers and bushings. It can be used on to trend PD activity in power transformers under load for assessing the insulation condition of bushings and windings over time. You can use the IP65-rated MONTESTO 200 both indoors and outdoors.
