静止式电能表静电放电抗扰度试验整改
Rectification of Static Electricity Meter for Electrostatic Discharge
Immunity Test
摘要 某三相静止式电能表的静电放电抗扰度结果不合格。通过采取在表盖液晶屏周围用绝缘胶水加强密封性、计量芯片复位端增加瓷片电容等整改措施,电能表通过了静电放电抗扰度试验。

Abstract The result of electrostatic discharge immunity test on a typical three-phase
static electricity meter was fail. Though analysis of the phenomenons, some methods
of improvement were carried out such as sealing the gaps between the meter cover
and LCD screen with insulating glue, and installing ceramic capacitor at the reset
terminal of metering chip. After rectification, the electricity meter passed the
electrostatic discharge immunity test.
