■ SEA Storm510X is a device for monitoring insulation faults in medium and high voltage ungrounded systems. It is suitable for three-phase AC systems and can contain extended DC loads. The device adopts the DC superposition method to superimpose the DC voltage and current signals on the running AC high-voltage system or electrical equipment. ■ The main functions of SEA Storm510X include monitoring the single-phase ground fault of the high-voltage line system, the insulation level of the busbar and each phase, phase failure, ground arc, abnormal voltage and abnormal leakage current. By monitoring these parameters, faults of lines or equipment can be detected and located in time, so as to avoid accidents that may cause more serious problems. ■ The design purpose of this device is to provide the monitoring function of offline or online insulation and single-phase grounding fault of lines and equipment in the power grid system, so as to ensure the safe operation of the power grid system.
