GB 4343.1—2003规定,不接地手持式器具需要加模拟手进行电源端子骚扰电压测量。通过实验介绍了电源端子骚扰电压测量中,不加模拟手与加模拟手时,测量结果的差异,并分析加模拟手后骚扰信号变大的原因及模拟手加在器具上不同位置的实际模拟效果,从而说明模拟手在电磁兼容测量中的重要性。
The national standard GB 4343.1--2003 specify that handheld appliances which are normally operated without an earth connection need to measure with artificial hand. Through the test of Mains terminals disturbance voltage introduced that the difference between these appliances with Artificial hand and without Artificial hand,and analyze the reason why the disturbed signal become stronger with Artificial hand and the actual simulation result with artificial hand putted different position of appliances. Finally, verified the importance of artificial hand in the EMC measurement.
