Abstract

The aim of the experiment was to observe
changes in individual measured dielectric or electrical
parameters by using different measurement methods and
their subsequent comparison. This paper will discuss in
detail the evaluation of individual measurements and
comparison of measurement methods implemented in the
framework of the experiment and the appropriateness of
their use for these types of measurements. In our
experiment cable samples, type 6-AYKCY 3x240, with PVC
insulation were used.
