Insulation Status Monitoring System for Low Voltage Direct Grounding Circuits (with Leakage Direction Function)

Depending on the circuit conditions, it is possible to choose between the Igr method and the Ior method for insulation monitoring!

Introducing the insulation condition monitoring system (with leakage direction function) for low-voltage direct grounding circuits, handled by Hikari Shoko, which engages in the manufacturing and sales of electrical equipment. The Igr/Ior switching type insulation condition monitoring device "LIG-2" backs up insulation monitoring by switching methods in circuits with high noise levels. It can complement the advantages and disadvantages of both Igr and Ior methods. The "LNV-1B" is a device that generates a reference voltage signal (20Hz, 10V) for monitoring insulation using the Igr method, and it is used in combination with a transformer (GM30B). 【Features (LIG-2)】 ■ Igr←→Ior method switching function ■ Backs up insulation monitoring by switching methods in circuits with high noise levels ■ Complements the advantages and disadvantages of both Igr and Ior methods ■ Numeric display function (displays current values and maximum values of Igr, Ior, and Io) ■ Leakage direction discrimination function ■ Stable detection unaffected by harmonic components due to digital filtering *For more details, please refer to the PDF document or feel free to contact us.
