Important “
Frequencies” lists the frequencies to be
used to perform the frequency sweep.
If edited (not recommended for standard
measurements),do NOT use any frequency
in the interval of line frequency ±3 Hz or
any multiple of the line frequency value
(e.g. 101 Hz for a 50 Hz system or 119 Hz
for a 60 Hz system is forbidden)
Models
Selection of what parameters to be available in graphs
and tables. The options are as follows:
C
Capacitance
%DF % Dissipation Factor (it will change to %TD if
%TD is selected in General)
%PF % Power Factor
C’’ The imaginary part of the complex
capacitance (C is capacitance AND the real
part of the complex capacitance. 1/Z = Y =
j*w*(C-jC’’)).
Analysis settings
Two modes of analysis are available based on single or
two materials.
Single material
Single material analysis is invoked when measuring
bushings, current transformers and other rather
homogeneous materials.
1]
Press “Edit Assessment Limits” to show a
dialogue window where modifications of
assessment limits for selected materials and
frequencies can be set.
Note Each Insulation type has its own limits.
2]
Press the “Edit Stop Frequency” button to
edit the suggested stop frequency value for
ITC1.
The suggested stop frequency value for
ITC1 Test is based on the object/insulation
temperature vs. stop frequency table.
3]
Press “Edit Materials” button to change
values of material used for analysis for
specific objects.
An instrument transformer typically has oil
impregnated Kraft paper while a bushing
may have an oil impregnated or resin
impregnated paper as an insulation material.
Default materials are OIP, RIP and Kraft
paper but more materials can be added.
