The purpose of this research is to construct experimental test set-up and to establish a series of performance test program for the domestically developed hydraulic couplings, and to provide a software to store and utilize these experimental data which can be used to improve the performance of the hydraulic coupling and solve the job problems confronted during operation. The performance test consists of measurement of torque, rpm and efficiency of the hydraulic coupling for three different amounts of working fluid with various loads to the output shaft, and investigating the torque, rpm and efficiency characteristics with respect to these parameters. The results of this study can contribute to the development of variable speed hydraulic coupling and torque converter pursued by the domestic industry.

LARGE SYNCHRONOUS GENERATORS USED IN CONNECTION WITH COMPRESSOR, TURBINE, IN MOST CASE, NEED THE HELP OF AN ELECTRICAL DRIVES FOR STARTING IN GAS TURBINES. NOWDAYS, THE STATIC FREQUENCE CONVERTER STARTING SYSTEM is EMPLOYED IN POWER PLANT. THIS PAPER DESCRIBES TORQUE CONVERTER, STATIC FREQUENCY CONVERTER AND COMPARSION OF TWO SYSTEMS.
