【摘要】 提出了因PT过载而产生的计量误差，并通过分析和计算，得出结论：10kV电压互感器过载造成的计量误差应同二次回路压降过大造成的计量误差一样引起重视，并应积极采取措施减少这种计量误差。更多还原

【Abstract】 A measuring error caused by PT overloaded is advanced. Through calculation and analysis, the concltlsion was obtained: The measuring error caused by10kV PT overloaded should be paid attention to as much as the error caused by thevoltage’s falling overmuch of the second loop and the programmes of decreasing themeasuril1g error should be adopted.更多还原
