Each Megger BITE product can measure internal cell impedance, inter-cell connection resistance and dc voltage of cells and jars. But only BITEs can be checked in the field for calibration validity to ensure quality of the data generated. This is because only Megger’s BITE instruments measure current simultaneously to potential.

Test instruments for the maintenance of electrical power systems

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.

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.
