RS232 to WiFi converter/RS485 to WiFi converter USR-W610 has passed EFT test, when there is instantaneous high current in the circuit (such as lightning, power switch, etc.), it can ensure that the device hardware is not damaged. Power: 2KV Ethernet interface 232 485: 2KV

Implementing PD tests in a substation/converter station is distinctly different than that carried out in a factory or a laboratory due to differences in test environment and testing equipment. Accurate PD analysis and identification can provide the right way to handle the defects of a transformer. Incorrect analytical results may result in

Jan 28, 20191. HVDC Converter Station. An HVDC converter station uses thyristor valves to perform the conversion from AC to DC and vice versa. The valves are normally arranged as a 12- pulse converter. The valves are connected to the AC system by means of converter transformers. The valves are normally placed in a building and the converter transformers
