NTC-05.08.1 “Electric measurements”
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 measuring electrical parameters and characteristics of electrical devices and elements are studied. Specifically, questions related to the determination and calibration of measurement instruments, expanding their measurement ranges through calculations of additional resistances and shunts, as well as methods for measuring signal amplitude using various detectors and oscilloscopes, are covered. Indirect methods for determining resistances of circuit elements using voltmeters and ammeters are also examined, along with bridge and resonance methods for precise measurement of resistances, capacitances, and inductances. An important part involves measuring deformation and temperature with specialized sensors (strain gauges, thermistors, thermocouples). Additionally, the operation of digital oscilloscopes for signal analysis is discussed, along with methods for measuring power in DC and AC circuits, including three-phase systems, and techniques for determining frequency and time intervals using oscilloscopes.
