Based on the discrete model of the stray current distribution, considering the mechanism of stray current on DC bias, the equivalent resistance model of the transformer DC bias caused by metro stray current was built with double銆唍d power supply environment. Then the calculation formula of ...
Magnetizing inrush current in transformer is the current which is drown by a transformer at the time of energizing the transformer. This current is transient in nature and exists for few milliseconds. The inrush current may be up to 10 times higher than normal rated current of transformer. Alt...
However, during the inference (generation) phase, the decoder cannot access the true target sequence and must instead rely on its own predicted output from the previous timestep as input for the current step. If the model makes an error at any given timestep, this mistake will propagate throu...
Scale-aware attention consists of global pooling layer, 1 × 1 convolutional layer, ReLU activation function layer and Hard Sigmoid activation function layer, and its main calculation formula is shown in the following Eq. (1)27, where \(f\) is the linear function similar to 1 × ...
(PA), which stands for the proportion of total pixels classified correctly over the total number of pixels of original samples. The PA value is closer to one, the segmentation is more accurate. The closer the value is to one, the more accurate the segmentation. The formula for calculation ...
The calculation formula for multi-head self-attention (MSA) module is shown as follows: \begin{gathered} {\text{MultiHead}}(X) = {\text{Concat}}({\text{head}}_{1} ,{\text{head}}_{2} ,...,{\text{head}}_{{_{h} }} ) \hfill \\ {\text{where head}}_{i} = {\text{...
If you want to know that how tofind the rating of transformer,Hereis a simple calculation for both 1-Phase & 3-Phase Transformers. you may Increase the Transformer Capacity, Improve the Power factor as The Transformer Capacity = Transformer Rating x P.f. ...
