Solar PV Energy

Photovoltaic energy, also known as solar photovoltaic power generation, is the process of converting solar energy into electrical energy based on the photovoltaic effect.
Compared with traditional fossil energy and nuclear power generation, photovoltaic power generation has many advantages.

Hydro Energy

Hydropower, also known as hydroelectric power, utilizes the potential energy of water located at higher elevations (such as rivers and lakes) flowing to lower elevations. This energy is converted into kinetic energy by water turbines, which then drive generators to produce electricity.

Railway

The power supply system for urban rail transit consists of the entire power supply system that delivers electricity to the trains running on the urban rapid transit line through high-voltage transmission networks, step-down at main substations, distribution networks, and step-down and rectification (converted to direct current) at traction substations from the power system.

What Impact Does The Transformer Ratio Have on The Power System?

What is transformer ratio？ The transformation ratio of a transformer refers to the voltage ratio between the high-voltage (HV) winding and low-voltage (LV) winding. Specifically, it represents the ratio of the rated voltage on the primary side (typically designated as the high-voltage or input side)
