Ring Wave Generator
Leave a Message
The RWG61000-12 series Ring Wave Generator is engineered to simulate ring wave interference phenomena encountered by electronic and electrical equipment under test (EUT) in operational environments. This interference includes damped oscillatory transients generated by high-voltage switching operations, transformer winding transients, and power system fault conditions. Through standardized immunity testing protocols, this generator evaluates the EUT’s tolerance to such conducted disturbances, facilitating the identification of insulation weaknesses and circuit immunity deficiencies to ensure reliable performance in complex power distribution networks.
The RWG61000-12 series is equipped with an intuitive Android-based touchscreen interface supporting both English and Chinese languages. It is deployed for electromagnetic compatibility (EMC) compliance verification across multiple sectors including LED lighting systems, medical devices, power electronics, industrial control systems, new energy charging infrastructure, small to medium-sized motors, low-voltage electrical apparatus, energy metering equipment, and household appliances.
