Introduction
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.
