摘要
The training stand for studying the connection schemes of electric energy meters is designed to train personnel working with electric energy metering systems. The training stand contains a power source (1), an electric load (2), a counter (3) of electric energy, a step-down transformer (4), a switch (5), a volt-ampere phase meter (6). The power consumption of the stand and its overall dimensions were reduced by supplying the stand with a step-down transformer, the beginning and end of the high voltage winding of which are connected respectively to the zero output of the power source and the first output of the load, which is connected to the phase output of the power source and the first current output of the counter, the beginning and end transformer low voltage windings are connected respectively to the second current terminal of the counter and the second terminal of the load, and the zero voltage terminal The meter is connected to the zero output of the power source. 1 ill.
