Insulation management in live line conditions: "New Proposal" Ior measurement enhances the efficiency of safety operations!
The increase in computers and inverter devices has significantly affected the capacitive current component in leakage current measurements. In this case, accurate insulation management cannot be achieved with leakage current (Io) measurements, and it becomes necessary to measure Ior.

basic information
Product Code: 30014 *Please provide this number when making inquiries for a smoother process.* ◆ Abundant Measurement Parameters: Pursue the causes of mysterious leakage breaker operation with measurement parameters! - Fundamental Wave Value: Io - Filter Value: Ifilt - Effective Value: Irms By simultaneously displaying the "Fundamental Wave Value Io," which extracts only the fundamental wave (50/60Hz) component from the measured leakage current waveform, the "Filter Value: Ifilt" obtained through filtering, and the "Effective Value: Irms" that includes harmonic components, you can confirm the effects of harmonics. ◆ Maximum, Minimum, and Average Measurement (REC Mode) If the measured values (instantaneous values) fluctuate and are difficult to read, or if you want to conduct long-term measurements using an AC adapter for one day or one week, you can check the maximum/minimum/average values in REC mode. ◆ Data Management on PC Data saved with the data management memory function can be downloaded to a PC via USB connection. The measurement data is in text format (CSV format). When you open the measurement file saved in REC mode, you can know the occurrence time of the maximum values of Io and Ior.
