How to Detect Converter Station pipes

At the receiving end the thyristor valves act as inverters to convert dc into ac which is utilized at the receiving end. Single line diagram of a HVDC transmission system is shown in Fig. 14.1, where A and B are the two converter stations. Converter station A is supplied from the generating station G.
