在逆变器认证中有GFCI（接地漏电流）测试，求测试方法。
是否是在正常启动完成以后接漏电测试仪即可？
软件测试行不行？外接1UF的电解电容，软件自动判断漏电流过大。在自动报警。

对单相设备做法是将火线和地之间接一个10K可调电阻，调节电阻值使得GFCI动作，同时记录一下火线和零线的电流值作为参考，并记录火线和零线的不均衡电流（可能是AC，可能是DC也可能都有）
% w7 ^& N( i* }  d! ]& ?5 MA GFCI is much more subtle. When you look at a normal 120-volt outlet in the United States, there are two vertical slots and then a round hole centered below them. The left slot is slightly larger than the right. The left slot is called "neutral," the right slot is called "hot" and the hole below them is called "ground." If an appliance is working properly, all electricity that the appliance uses will flow from hot to neutral. A GFCI monitors the amount of current flowing from hot to neutral. If there is any imbalance, it trips the circuit. It is able to sense a mismatch as small as 4 or 5 milliamps, and it can react as quickly as one-thirtieth of a second.

包子，这个测试是不是有专门的仪器测的？？
