变压器容量现场测试方法研究

Research on Field Measurement Method of Transformer Capacity

变压器容量现场测试的关键是要获取准确的短路阻抗值。文中详细说明了一种较直观的短路阻抗估算方法,以方便缺少短路阻抗信息的变压器进行容量现场测试,降低变压器容量评估成本。

The key of transformer capacity field test is to obtain accurate short-circuit impedance value.In this paper,a more intuitive shortcircuit impedance estimation method is described in detail to facilitate on-site capacity testing of transformers lacking short-circuit impedance information and reduce the cost of transformer capacity evaluation.
