Widely used for factory inspection, handover acceptance, overhaul and preventive tests on generators, transformers, cables, motors, switchgears and high-voltage equipment. It offers safety reference for withstand voltage tests and equipment commissioning and avoids insulation breakdown, leakage and short-circuit failures.
Self-Calibration for Reliable Measurement Accuracy Built-in self-calibration function helps maintain measurement accuracy and enables convenient on-site calibration when required.
Advanced Insulation Diagnostic Functions Powered by an 8-bit microcontroller with an intuitive Chinese-language interface, the tester automatically performs Dielectric Absorption Ratio (DAR) and Polarization Index (PI) measurements. It also supports withstand voltage testing and quick test modes.
High Test Output with 5 mA Short-Circuit Current Delivers a short-circuit current of ≥5 mA, providing stable charging current and reliable performance for high-voltage insulation testing.
Excellent Anti-Interference Performance Advanced circuit architecture and digital filtering technology provide strong resistance to electromagnetic interference, ensuring stable and reliable measurements in complex high-voltage field environments.
Rugged, Portable & Long-Lasting Design Designed with electromagnetic compatibility and impact resistance in mind, the instrument features a rugged safety enclosure for demanding field applications. The built-in 2600 mAh rechargeable lithium-ion battery and intelligent charging system provide extended operating time and convenient field use.
Comprehensive Safety & Fault Protection Multiple protection functions, including short-circuit, overload, and automatic discharge protection, enhance operational safety. Audible and on-screen alarms provide timely warnings during abnormal conditions.
