Current Leakage Tester
A Current Leakage Tester is an electrical measuring instrument used to detect and measure leakage currents in electrical equipment, appliances, and wiring systems. Leakage current is the unintended flow of electric current from a live conductor to the ground or other conductive parts, which can pose safety hazards, cause equipment malfunction, or increase power losses. These testers are widely used in quality control, safety inspections, electrical maintenance, and compliance testing to ensure that electrical devices meet safety standards (such as IEC, BIS, or UL standards).
- Measurement Range: Capable of measuring very low leakage currents, typically from microamperes (µA) to milliamperes (mA).
- High Accuracy: Provides precise readings for leakage current to ensure safety compliance.
- Multiple Test Modes: Can test under different operating conditions – normal, reversed polarity, or with/without grounding.
- Digital/Analog Display: Available with digital LCD display for easy reading, or analog scale for trend observation.
- Portable Design: Lightweight and handheld models for field testing, as well as benchtop models for laboratory use.
- Auto Range & Auto Zero: Automatically adjusts measurement range and cancels offset errors.
- Alarm Function: Audible/visual alarm if leakage current exceeds preset safety limits.
- Clamp-On Type Option: Some testers use a clamp design for non-invasive leakage current measurement without disconnecting wires.
- Compliance Testing: Meets international standards for electrical safety testing.
- Data Logging & Connectivity: Advanced models include memory storage, USB/Bluetooth connectivity for analysis and report generation.
