Current Transformer (CT)

The current transformer's turn ratio is a key specification that determines how it scales down high currents to safe levels for measurement and monitoring. In this case, the turn ratio is 30/5, which means the primary winding has 30 turns of wire, while the secondary winding has just 5 turns. This setup allows the transformer to step down the current by a factor of 6, making it suitable for applications where low currents need to be measured or monitored accurately.
