Nowadays, due to the expansion of the electricity distribution network and the need to meet the requirements of various consumers, maintaining the stability and quality of electricity is very important. With the increase in the number of subscribers and the expansion of distribution networks, voltage drops in network lines have become a major challenge. To stabilize consumer voltage and improve network reliability, the use of distribution transformers with on-load tap changers is expanding as an effective solution.
Conventional transformers with off-circuit changers cannot quickly respond to the changes in production and consumption that occur throughout the day and night. Therefore, using transformers with on-load tap changers is the best option in this situation. Additionally, distribution transformers with on-load tap changers are widely used in industries. In large industries with high-power electromotive loads, maintaining stable grid voltage during the startup and shutdown of electric motors is critical. Only distribution transformers with on-load tap changers can meet such a need.
Arya Transfo Industrial Group, has designed and supplied distribution transformers with on-load tap changers to solve the problem of voltage stability in the distribution network. These transformers are equipped with voltage regulation relays and current sampling transformers, allowing for automatic adjustment of the output voltage according to the network load.
