In this thesis I presented the process of testing an electricity meter. Testing needs to be
done, so that the manufacturer can sell his measuring equipment on the market. In the
first part of the thesis I described the theoretical background of electricity meters, basic
statistics and measurement uncertainty. I also described the legal background, which
applies to measuring equipment testing and basic demands and conditions which apply to electricity meters. Checking the adequacy of measuring equipment is implemented with
the use of modules – processes for checking of compliance. The test I performed are
described in an international standard. It consists of conditions, goals and limit values of
measurement errors. I tested the meter with a measuring system, which consisted of a
power source, a nationally accredited reference meter, and measuring heads. I set the test conditions with the use of computer software. I described three of the tests I performed,
the measuring results and checking, if the meter passed the tests successfully.
