NTC-05.08 “Electric measurements”

Br0.00

The educational laboratory stand is intended for use as training equipment for conducting laboratory work in the course “Electrical Measurements.” During these labs, methods and tools for verification, calibration, and expanding the measurement ranges of electrical instruments are studied, along with methods for indirect and direct measurement of electrical parameters. Specifically, issues related to determining the accuracy and class of instruments (amperemeters, voltmeters, wattmeters, energy meters), their calibration schemes and methods, as well as calculating shunt resistances and additional resistors to extend measurement limits, are covered. Methods for measuring small resistances indirectly and determining power factors under various loads are also studied. An important part involves mastering techniques for measuring inductances and active power in three-phase circuits using appropriate instruments. Additionally, the application of electronic oscilloscopes for measuring voltages, currents, and frequencies is examined, along with their device structure and operational rules.
