Product Description

Digital Electricians Portable Insulation Resistance Meter

High Voltage Megohmmeter Megohm Resistance Tester for Transformer applications, designed for professional electrical testing in demanding industrial environments.

Key Features & Benefits

Superior Anti-Interference for Live Substation Testing: Exceptional anti-electric field interference capability up to 2mA (50Hz), enabling insulation resistance testing of 500kV large-scale transformers without removing overhead lines. Powerful noise rejection eliminates extensive disconnection work, dramatically reducing testing time and enhancing safety in high-voltage substation environments.
High Short-Circuit Current for Large Inductive Loads: Engineered with 10mA short-circuit current output, specifically designed for testing high-capacity transformers and high-inductance equipment. Robust current capability ensures rapid charging of large inductive loads, delivering stable insulation resistance readings on massive power apparatus.
Ultra-Wide Resistance Measurement Range: Covers extensive range from 0.01MΩ to 1999GΩ with high resolution, providing accurate readings across diverse applications from low-resistance equipment to high-value insulation systems. Ideal single instrument for testing everything from small motors to large power transformers and high-voltage cables.
Broad Adjustable Output Voltage: Flexible output voltage selection including 0.5kV, 1kV, 2.5kV, 5kV, 10kV, and 20kV, with smooth continuous adjustment from 0V to any desired value. Versatility enables comprehensive insulation testing across multiple voltage classes, allowing technicians to perform polarization index, dielectric absorption ratio, and step-voltage tests with a single instrument.
