But in this case, we needed to account for power flowing back into the grid during peak solar production. The diagram used special arrows and notations to clearly show how power could flow in both directions through the transformer.

Another interesting case was a project for a manufacturing plant with sensitive electronic equipment. The transformer diagram included symbols for harmonic filters and power factor correction capacitors. These components are crucial for maintaining power quality in industrial settings. The diagram helped us plan the optimal placement of these devices in relation to the transformer windings.

Smart grid integration has been a growing trend, and the diagrams have evolved to reflect this. In a recent urban modernization project, I worked with transformer diagrams that included symbols for communication modules and remote sensing equipment. These diagrams helped us plan the integration of the transformers into the city's smart grid network, ensuring seamless data flow and remote management capabilities.
