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.

Measuring Jars with Multiple Cells using PowerDB
A battery consists of a jar that can contain multiple cells. When performing battery testing, it is recommended to take measurement on the individual cell if possible. However, with most batteries it is only possible to take measurements on the jar. Since this is the smallest unit that can be replaced, this makes sense. Yet some batteries that have multiple cells also have multiple posts that allow for the measurements of the cells within the jar. For this reason we allow PowerDB to be configured for this application and this paper explains how to do that.

Field Calibration Verification
Each Megger BITE product can measure internal cell impedance, inter-cell connection resistance and DC voltage of cells and jars. This paper looks at how the BITE can be checked in the field for calibration validity to ensure quality of the data generated.

IEC 61850 GOOSE Interoperability
GOOSE messaging can today be considered a working technology. In order to commission substations with the new IEC 61850 technology, there is need to use some new tools and methods. The key for these tools and methods is, paradoxically, implicitly available in the IEC 61850 standard itself.

Guide to transformer winding resistance measurements
Measuring a transformer's DC resistance from one external terminal to another can reveal a great deal of information about the transformer. In addition to the obvious faulted winding (i.e., an open winding or shorted turn), more subtle problems can be detected.

Testing electric vehicle supply equipment
Most installations require an additional connection to ground at the charging point, so that there is still a form of protection under fault conditions. This connection would be made by an earth spike/electrode driven into the ground.
