Blog Article
The TY6045 is a digital insulation resistance tester (megohmmeter) designed for measuring insulation resistance in electrical systems, cables, motors, and other high-voltage equipment. Here’s a detailed breakdown of its features, applications, and usage:
Key Specifications
Test Voltage Ranges
Common ranges: 250V, 500V, 1000V, 2500V, 5000V (covers low- to high-voltage systems).
Auto-discharge function for safety after testing.
Measurement Range
Insulation Resistance: 0.01 MΩ to 10 TΩ (terohms) for precise leakage detection.
Polarization Index (PI) & Dielectric Absorption Ratio (DAR): Advanced diagnostic modes for insulation health.
Display & Interface
Large LCD backlit screen with clear digital readouts.
Bar graph display for trend visualization.
Safety & Compliance
CAT IV 600V / CAT III 1000V (suitable for harsh industrial environments).
Meets IEC 61010-1, IEC 61557 (safety and accuracy standards).
Power Supply
Rechargeable Li-ion battery (long runtime) or AC adapter.
Typical Applications
✔ High-Voltage Equipment Testing (transformers, switchgear, generators).
✔ Cable & Motor Diagnostics (identifies moisture, aging, or contamination).
✔ Industrial Maintenance (preventive checks per IEEE 43/IEC 60335).
✔ Solar Panel & EV Systems (insulation integrity checks).
How to Use the TY6045?
Prepare the System
Ensure equipment is de-energized and discharged.
Disconnect all loads and clean test surfaces.
Select Test Voltage
Match voltage to equipment rating (e.g., 1000V for 480V systems).
Connect Test Leads
Red (Line) → Conductor, Black (Earth) → Ground/Shield.
Use Guard Terminal (G) to eliminate surface leakage errors.
Start Test
For PI/DAR tests, run for 1 min + 10 min (per IEEE 43).
Interpret Results
>1 MΩ: Acceptable for most equipment.
>100 MΩ: Excellent (critical systems).
PI ≥ 2.0: Healthy insulation (PI = 10-min/1-min resistance).
