| Abstract: | Along with the urgent needs of raising power system automation level and power market devetopment, it is more important for further improving the accuracy of online measuring reactive power, voltage and current and its inspection on - the - spot. According to the present situation of measuring reactive power, voltage and current and its inspection on - the - spot, the paper put forward the measures of adopting Hall current sensor, digital measuring instrument, and precise sprit core transformer. The solving method for raising accuracy of the measuring reactive power, voltage and current and its inspection on - the - spot was discussed and received the expected effect. |
