13.6.4 Correction procedure

Electrode systems with guarding and suitable connections ensure a precise measurement by shunting

edge currents from spurious external voltages away from the measuring circuit. This reduces the

probability of a measurement error significantly. In theory the edge capacitances c

are zero.

Nevertheless, stray capacitances of the test cell or between the leads and to ground are not shunted.

The presence of such capacitances could still influence the measurement accuracy, for example, of thin

samples (µm range). We recommend to

•

Perform a standardized air reference measurement using the SPECTANO Analyzer Suite

•

Activate the correction to display the corrected capacitance and relative permittivity ε

values.

For more information about the air reference correction and its equations read chapter 10.4

Perform reference measurements.

13.7 Cylindrical electrode without Guard ring

13.7.1 IEC standards

According to the IEC standards for the analysis of dielectric and resistive properties of solid and liquid

insulating materials

•

IEC 60250-1969: AC methods for solid insulating material analysis

•

IEC 60247-2004: AC methods for liquid insulating material analysis

•

IEC 62631-3-1-2017-03: DC methods for solid insulating material analysis

you can use a Cylindrical electrode test cell without Guard ring for AC and DC method analysis.

IEC 60250-1969 is replaced by IEC 62632-2-1-2018-2. The following table describes the differences

between these two standards:

In comparison to IEC 60250, the latest IEC standards such as IEC 62632-2-1-2018-02 base on the

demands on different frequency ranges.

Cylindrical test cell types are not described anymore in the latest IEC standard for the analysis of

dielectric properties of solid insulating materials.
