Advanced Variable-Frequency AC Induced Withstand Voltage Test Set for Partial Discharge Test
The SXGY Series Triple-Frequency Induced Overvoltage Tester represents one of the most rigorous and effective methods for evaluating the insulation strength of power equipment. This advanced system is designed to detect concentrated high-risk defects and plays a decisive role in determining whether electrical assets can safely remain in service.
Designed in compliance with the latest national power industry standards, this device performs comprehensive insulation strength tests on electrical products, components, and insulating materials at specified voltages. It assesses insulation levels, identifies defects, and verifies overvoltage withstand capability.
Key Features
- Operation source configuration monitoring function: High voltage, low voltage current, timing indication
- Comprehensive protection functions: Over-current protection, over-load protection, over-heat alarm reminder
- Advanced time relay with wider timing range
- High-voltage coil constructed with multi-layer tower design using high-quality polyester enameled wire
- Test transformers (above 5kVA) equipped with movable iron wheels for mobility
- Wide frequency range (45-400Hz) for comprehensive high voltage partial discharge testing
