Low voltage direct grounding circuit I0r detection method insulation state monitoring device

Equipped with leakage direction functionality! Enables insulation monitoring with a higher accuracy I0r value that is more aligned with actual conditions!

We would like to introduce the "LSIG-8/LIG-11," an insulation monitoring device with leakage direction functionality for low-voltage direct grounding circuits, handled by Hikari Shoko, which manufactures and sells electrical equipment. The I0r detection method detects not only the current (I0) identified by the ZCT but also the circuit voltage. Based on this voltage, it calculates and removes the current flowing through the capacitive component (reactive component: I0c) to isolate and detect only the current flowing due to insulation resistance (active component: I0r). Our I0r detection method adopts a system that inputs the actual voltage between the circuit and ground, rather than the line-to-line voltage of the circuit, allowing for more accurate insulation monitoring based on a realistic I0r value. 【Features (LSIG-8)】 ■ I0r detection method insulation monitoring device with 8 circuit aggregation ■ Equipped with functionality for 8 circuits ■ Stores and displays numerical data from the last 10 alarm activations *For more details, please refer to the PDF document or feel free to contact us.
