مشخصات:
On-line measurements of partial discharges are the only technology available on the market to qualify its stator winding insulation, when a generator or another rotating machine is in service.
The great advantage is that all thermal, electrical, ambient and mechanical forces are present. On-line measurement of partial discharges requires a partial discharge sensor (often called a coupling capacitor) at each phase output.
Once the partial discharge sensors are installed, online measurements can be performed either periodically with a portable partial discharge analyzer or continuously with a permanently installed monitoring system. In addition to the partial discharge signals, this system also acquires operating parameters such as winding temperatures and load conditions to correlate them with the measured partial discharge results.
