Routine test report
Together with instrument transformer are deliv-
ered:
• routine test report;
• two rating plates (one plastered on the trans-
former and one free).
The following information can be included on the
request. These are free of charge:
• theoretical current/voltage errors and phase
displacement values;
• theoretical excitation curves.
There are additional extra paid reports which can
be supplied on request:
• accuracy test report;
• magnetizing curve (for current transformers);
• additional labels (if more than 2);
• verification tests.
5. Instructions for maintenance
Visible surface pollution shall be cleaned off the
transformer. Polluted transformer can be cleaned
by alcohol. In case of surface contamination
please contact the manufacturer.
6. Transport and storage
Temperature for transport and storage the indoor
transformers is from -25°C to +70°C. During
transportation and storage the transformers
must be protected from direct sunlight.
The transformers are shipped in wooden boxes or
mounted on the pallets. Other temperature must
be agreed by the manufacturer.
7. Disposal
Materials used in instrument transformers are
considered as materials without dangerous envi-
ronmental impact and materials are not toxic.
Disposal of instrument transformers is controlled
by national legislation of communal waste.
8. Handling with the transformers
Handling with the transformer is described in the
Appendix 4.

Operation of electrical installa
tions
Current and Voltage transformers are designed,
tested and produced according to international
or national standards required by customers and
agreed by producer. Specific standard is always
mentioned on the Rating plate of transformer.
For example these standards:
IEC 60044-1; IEC 60044-2; IEC 60044-6; IEC
61869-1, IEC 61869-2; IEC 61869-3

CSA Std CAN3-C13-M83
GOST 1516.3-96; GOST 7746-2001
BS 3939:1973; BS EN 61869-2
If it is agreed between customer and producer it
is possible to deliver also other standard or stan-
dards which are mentioned above with different
revision.
