STB 32 – Electrical Machines and Power Electronics Laboratory
In the Electrical Machinery Lab, working principles and characteristics of DC and AC electric motors and power generators are examined. Transformer experiments cover conversion ratio, mono phase transformer short circuit, loaded, and unloaded working, and mono phase transformer polarity determination. DC electrical machine experiments cover externally excited DC generator unloaded working characteristics and load characteristics. Asynchronous electrical machine experiments cover asynchronous electrical machines unloaded working, and three-phase asynchronous electrical machines loaded working.
The laboratory also has Power Electronics Training Sets. They are designed to execute the applications of basic Power Electronics, industrial automation studying and using the control and measuring of electrical operations, recognition of the circuit elements, analysis, and application development. The Set consists of a multi-function Lab desk and Energy units, measurement modules, load groups, and the necessary accessories. The Set contains experiments that can be done with rectifiers, phase-controlled rectifiers, AC-AC converters, DCDC converters, and inverters.
The experiments conducted in this laboratory are as follows:
1. No-Load Characteristic of Synchronous Generator
2. Exterior Characteristic of Synchronous Generator
3. Finding the Slip (s) of the Induction Motor
4. Determining the Turns Ratio of a Single Phase Transformer
5. Open – Circuit Test of a Single Phase Transformer
6. Short – Circuit Test of a Single Phase Transformer
7. Voltage Regulation and Efficiency of a Single Phase Transformer Rectifiers with Diodes
8. Rectifiers with Thyristor
9. Three Phase Controlled Rectifiers
10. DC-DC Converters
