The aim of the diploma is to present the standards related to electrical meters, as well as some metrological requirements and to present the requirements of the safety standard for electricity meters IEC 62052-31 in more detail. Some metrological requirements tests were performed, such as measuring the meter’s error at different currents and measuring the influence of temperature on the meter’s error. In addition, the requirements for the light-emitting diode used for the test measurements are checked. The IE.5 EB2 electricity meter, on which the tests were performed, is also described, along with the role of individual connections. In the safety part, the standard requirements are generally described and presented in more detail for tests that could be performed in the measurement laboratory of Iskraemeco d. d.. Based on the requirements of the standard, we checked the compliance of warning labels and information on the meter, measured heating of the housing, connection and components, confirmed that parts under dangerous voltage are not accessible, checked the insulation between accessible parts and parts under dangerous voltage, performed inspections and tests related to constructional requirements for the housing and connections of the meter and performed electrical safety tests. We found that the meter is in compliance with the metrological and safety requirements that we were able to check.
