Advanced and designing experiments (Exemplary experiments for electro technology and circuit) Besides the convention experiments meeting the short term teaching requirements, the GDDS high performance electrics and electronics experiment device can also satisfy the demand for advanced and designing experiments for medium term teaching requirement without adding any instruments to fully realize the open type optimized experimental teaching mode. Here we listed some experiment items which have higher requirements on the testing technique, precision, methods, depth and extent of knowledge and the operating ability than the conventional experiments have. A certain amount of conventional experiments and basic training are needed for students before doing these experiments. (1)Designing of phase sequence indictor (2)Analysis of the non- sine periodic circuit and harmonics (3)Designing and testing of the circuit in step voltage generator (4)Test and principle of single phase and three phase leakage protection circuit (5)Design of phase shifting bridge circuits and phase test (6)Connecting methods of three phase transformer and the obtain of specific phase (7)Characteristics of gyrator and design of parallel resonance circuit (8)Design and characteristic test of passive filter (9)Design and characteristic test of active filter (10)Measuring methods of the reactive power and active power in single phase and three phase circuits
