| Abstract: | NSG1025 fast transient/burst interference generator. which cooperates with the IEC801-4 standard. is adopted to simulate the interference of microprocessor-based protective device under practical operation conditions. Using the newly developed protective device (prototype device) as the tested object. some measures about imploving anti-interference ability of protective device are suggested based on testing. improving and comparing. These measures are used to block the coupling channel of common mode interference. to promote the anti-interference ability of the sensitive circuit and to design the grounding and bleeder circuit rationally. |
