swell test

The results show that in the test process, the varia-tion of the swell stress curve with time can be divided into three segments.

结果表明：GCL吸水膨胀应力在测试过程中随时间的变化可明显分出3个阶段，即：应力快速增加，应力缓慢增加和应力平缓波动阶段。

The four typical power quality disturbances of voltage sag, swell, interruption and transient impulse are used to test the proposed method, the effectiveness of which is verified by the simulation results.

对包括电压凹陷、电压上升、瞬时断电和暂态脉冲在内的4种典型电能质量扰动进行了测试，仿真结果表明了该方法的有效性。
