Laboratory for Electrical Quantities

ACTIVITIES

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


NATIONAL STANDARDS

National standard is the digital multimeter, manufactured by FLUKE, type 8508A. With a 8,5-digit resolution, exceptional linearity and low noise, digital multimeter FLUKE 8508A ensures the most accurate measurements to be had from any commercially available measuring instruments today in the field of voltage, current and resistance measurements. Along with the accuracy of the multimeter its stability is also very important. Multimeter FLUKE 8508A ensures long-term stability of 2,7 ppm, and short-term stability of 0,5 ppm, ensuring the confidence in measurement all throughout the year.

Multimeter FLUKE 8508A can replace 8 measuring instruments:
• multimeter;
• resistance bridge;
• voltage divider;
• null detector;
• AC/DC transfer;
• thermometer;
• AC/DC resistors;
• picoammeter.

With ranges from 200 mV to 1 kV for voltage measuring and frequency range up to 1 MHz for AC measuring FLUKE 8508A covers all measuring of the low frequency voltage. 8, 5-digits resolution is available on all ranges. Exceptional linearity, coupled with Ratio measurement capability, means that FLUKE 8508A multimeter can replace Kelvin Varley dividers and AC/DC voltage transfer standards. Ranges for current measuring are from 200 μA to 20 A at a frequency of 1 Hz to 100 kHz for the measurement of alternating current. FLUKE 8508A multimeter can measure resistance within ranges from 2 Ω to 20 GΩ, with a possibility of choosing resolution from 5,5 to 8,5 digits.

SCOPE OF ACCREDITATION OF THE LABORATOR FOR ELECTRICAL QUANTITIES

ATCG HAA 1


VERIFICATION OF THE MEASURING INSTRUMENTS

Laboratory for Electrical Quantities carries out an examination of electrical quantity measuring instruments in order to determine compliance with the prescribed metrological requirements with the aim of their verification.


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 Quantities carries out a procedure for issuing a Decision on the type approval of the measuring instruments in the field of electrical quantities measuring, 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):
• measuring instruments for testing the protection measures in electrical engineering.


TRACEABILITY SCHEME

Laboratory for electrical quantities accomplishes traceability by a digital multimeter, manufactured by FLUKE, type 8508A. Laboratory for electrical quantities does the external calibrations of its reference standards and equipment, at 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.
