Product Description

RLM-33+ Professional-Grade Electrical Insulation Resistance Tester

Specifically designed for testing the insulation performance of electrical equipment and circuits. Its core functions and typical applications are outlined below.

Core Functions

Insulation Resistance Measurement: Measures insulation resistance values (typically ranging from 0.1 MΩ to 2000 MΩ or higher) with selectable test voltages (e.g., 250V, 500V, 1000V, 2500V) to match different equipment standards.
Polarization Index (PI) & Absorption Ratio (DAR) Testing: Calculates PI (10min/1min resistance ratio) and DAR (60s/30s resistance ratio) to assess the long-term insulation stability of devices like transformers or motors.
Continuity Testing: Checks the continuity of low-resistance circuits (e.g., wires, switches) with audible/visual alerts, ensuring no open circuits or high-resistance connections.
Data Storage & Transfer: Stores multiple sets of test results (resistance values, test voltage, timestamp) and supports data export via USB or Bluetooth for report generation.
Safety Features: Equipped with overvoltage protection (OVP), short-circuit protection, and a double-insulated housing to ensure user safety during high-voltage testing.

Typical Applications

Electrical Equipment Maintenance: Used to test insulation of motors, generators, transformers, and cables in factories, ensuring they meet safety standards and preventing insulation breakdown.
Power Distribution System Inspection: Evaluates the insulation performance of switchgear, circuit breakers, and power cables in commercial buildings or power plants before commissioning or after maintenance.
Electrical Safety Audits: Conducts mandatory insulation tests on electrical appliances (e.g., industrial machinery, household devices) in compliance with safety regulations (e.g., IEC, ANSI).
Cable & Wire Testing: Checks the insulation integrity of new or aged cables (power cables, control cables) to detect defects like moisture intrusion or physical damage.
Renewable Energy System Testing: Tests insulation for components in solar PV systems (inverters, combiner boxes) and wind turbines to ensure reliable operation in outdoor environments.
