Vanliga problem med strömkvalitet: Transienter
En transient defi nieras enligt IEEE 1159 som ett fenomen eller en kvantitet som varierar mellan två efterföljande jämviktstillstånd under ett kortare tidsintervall sett till den aktuella tidsskalan. En transient kan vara en enkelriktad puls med valfri polaritet eller en dämpad oscillerande våg med den första toppen i endera polaritet.

UHF PD Diagnosis at high voltage cable terminations
High voltage terminations are essential components in high voltage cable systems. Great reliability is provided by high manufacturing quality and company type testing. However, onsite installations represent a considerable uncertainty for successful service of the system. UHF PD Diagnosis has proven to be a valuable and effective method for measuring high voltage assets because this online measurement is performed at frequencies which are not affected by environmental noise.
