Research and production laboratory for measurement the parameters of electrical circuits and electrical energy
(laboratory № 25-2)

The laboratory conducts such types of metrological works:
Conformity assessment of legal measuring instruments (MIs):

• electricity meters;
• MIs of electrical parameters of electrical installations equipment;
• MIs of electrical AC/DC resistance, capacitance, inductance and mutual inductance.

Calibration of MIs:

• short circuit current testers;
• electrode system simulators;
• standards and decades of electrical AC/DC resistance, capacitance, inductance and mutual inductance;
• standard cells (DC voltage sources);
• AC and DC bridges;
• digital ohmmeters, microohmmeters;
• voltage dividers and potentiometers;
• portable digital meters of inductance, capacitance and electrical DC/AC resistance;
• test equipment for electricity meters;
• shunts.

Verification of legal MIs:

• electricity meters in the lab and on - site;
• standards and decades of electrical DC/AC resistance, capacitance, inductance and mutual inductance;
• digital meters of electrical resistance, capacitance, inductance and mutual inductance;
• DC/AC bridges.

Electrotechnical measurement of:

• ground loop;
• resistance of insulation;
• "phase-zero" resistance loop.
