The on-site test results indicate that energy meter's neutral point virtual connection has a great effect on PT secondary voltage drop.
基于对称分量法，对电能表中性点虚接后的电压互感器二次压降进行了分析，得出了正确接线前后的计量误差变化量。
The voltage drop in the secondary wiring connecting the meters with the voltage transformer affects seriously the accuracy of measurement.
电压互感器至电能计量仪表之间二次线上的电压降，对计量精度有重要影响。
This can even happen for a small DG located on the secondary because of the voltage drop along the service drop, the secondary wiring, and the distribution transformer.
当次级侧的分布式发电功率很小的时候，也有可能引起高电压，这是由于架空线路、次级线包和配电变压器上的电压降引起的。
