KEW 3125, or more specifically KEW 3125A, is a high-voltage insulation tester manufactured by Kyoritsu (KEW). It's a tool used for measuring insulation resistance, often in industrial settings or by electricians.
Key features and capabilities:
High Voltage Testing: It can test insulation resistance at high voltages, ranging from 250V to 5000V.
Wide Measurement Range: It can measure insulation resistance up to 1 Tera-ohm (TΩ).
PI and DAR Diagnosis: Includes features for Polarization Index (PI) and Dielectric Absorption Ratio (DAR) measurements, which are used to assess the condition of insulation.
