Laboratory for Electrical Power

ACTIVITIES

Activities performed at the Laboratory for Electrical Power are related to:
• Realization, conservation, maintenance and improvement of the national standard for electrical power in Montenegro;
• Ensuring metrological traceability in the field of electrical power in Montenegro through the transfer of the electrical power unit from the national standard to the secondary and working electrical power standards;
• Development of the measuring methods for transferring the electrical power unit;
• Laying down the prescribed technical and metrological requirements for determining the measuring instrument type for electrical power measuring instruments;
• Participation in inter-laboratory comparisons;
• Verification of the electricity meters.


NATIONAL STANDARD

National standard is the standard device for testing the electricity meters from manufacturer MTE, type PTS 400.3. Accuracy class is 0,02, and it is utilized for measuring active, reactive and apparent energy measurement in three-wire or four-wire circuit with integrated error measurement. Laboratory for Electrical Power has capabilities for simultaneous testing of three electricity meters of accuracy classes 0,2S; 0,5S; 1 and 2, active electrical power and accuracy classes 2 and 3 of reactive electrical power. Transferable reference standard PRS 400.3 has further functions integrated:
• Simultaneous testing for up to three measuring instruments or testing of a multifunctional measuring instrument;
• Internal memory for measurement results;
• Vector diagram;
• Active, reactive and apparent energy measurement in three-wire and four-wire circuit with integrated error measurement;
• Voltage measurement, as well as the current measurement, directly or through the current transformer;
• Active, reactive and apparent energy measurement;
• Phase angle, power factor and frequency measurement.

 
VERIFICATION OF MEASURING INSTRUMENTS

Laboratory for Electrical Power carries out an examination of electricity meters in order to determine compliance with the prescribed metrological requirements with the aim of verifying the electricity meters:
• electricity meters of accuracy classes 0,2S; 0,5S; 1 and 2 active electrical energy;
• electricity meters of accuracy classes 2 and 3 reactive electrical energy.


TYPE APPROVAL OF MEASURING INSTRUMENTS
In order to ascertain compliance with the prescribed technical and metrology demands, to determine type of measuring instrument, Laboratory for Electrical Power carries out examination of electricity meter type, in accordance with the Decree on legal measuring instruments that are mandatory subjected to verification and/or the type approval of the measuring instrument (Official Gazette of Republic of Montenegro, No. 81/09).

TRACEABILITY SCHEME
Laboratory for Electrical Power is responsible for obtaining the metrological traceability in the field of electrical power measuring in Montenegro, i.e. transfer of the electrical power measuring units to the end users. Laboratory for Electrical Power achieves traceability through the standard device for testing the electricity meters, and which of calibration is conducted in the laboratories of national metrological institutes, that have CMC published in the database of BIPM.

Traceability in the field of electrical power measuring is being realized with the help of the standard device for testing the electricity meters, from manufacturer MTE, type PCS 400.03, accuracy class of the device is 0,02 %, which of calibration is being conducted regularly in the laboratories of national metrological institutes, or authorized institutes (EURAMET Designated Institutes) that have published CMC at BPIM KCDB, or are accredited by an accreditation body signatory to the EA MLA agreement.
