      1.Product Overview

      Suitable for small current supply systems with voltage levels of 380V, 3kV, 6kV, 10kV, 35kV and 66kV neutral points that are not grounded or grounded via arc suppression coils. When ferromagnetic resonance, grounding or overvoltage faults occur in the system, the ferromagnetic resonance fault is eliminated and recorded, and single-phase grounding and overvoltage faults are monitored and recorded. Note: This device can only eliminate non-permanent ferromagnetic resonance faults induced by external causes, and other PT overvoltages caused by persistent external factors cannot be eliminated.

      2.product features

      SMR-WXA series microcomputer-type resonance elimination device is a new type of development and production based on the widespread consultation of users for the vicious accident of voltage transformer (PT) burning and even explosion that often occurs in the power system due to ferromagnetic resonance. Intelligent harmonic elimination device. With high-performance ARM chip as the core, through the export of high-power, non-contact harmonic elimination components, liquid crystal display (LCD), signal indicator, touch button for human-machine interface, with intelligent software, constitutes advanced technology and principles, Simple and convenient intelligent resonance diagnosis, elimination and recording device. Compared with similar devices, it has the characteristics of high integration, strong anti-interference ability, small size, light weight and quick action.
