The load state of a transformer refers to the load it bears during actual operation, which reflects the working condition and health level of the transformer.Copper loss (also known as wire loss or resistance loss) is the energy loss caused by the current passing through the winding of a transformer

Demagnetization refers to the elimination or reduction of residual magnetism accumulated in power equipment due to long-term operation through specific methods. Residual magnetization can have adverse effects on the performance and safety of equipment, therefore demagnetization is one of the importa

The current generated when a direct current voltage is applied at both ends of the insulation material can be divided into two parts: volume leakage current and surface leakage current. The current values of these two parts are generally very small, measured in microamperes (μ A); The size of the l

I、 Concept: Refers to the distortion of current or voltage waveforms, which is a sine wave component that is an integer multiple of the fundamental frequency. For example, in a 50Hz power system, 100Hz, 150Hz, 200Hz, etc. are all harmonics.II、 Causes: Mainly caused by nonlinear loads, such as freq
