LFY-421 Electrical Insulation Performance Tester

Main application
Used for the determination of electrical insulation performance, including resistance to high-voltage impact, high-voltage insulation resistance, and high-voltage breakdown time. Technical characteristics
1. A dedicated high-voltage boosting device is used to generate continuous adjustable AC high voltage.
2. The AC high voltage is digitally displayed, and the high-voltage breakdown time is also digitally displayed.
3. It can be pressurized at a set time, and the high voltage will automatically be turned off when the time is up.
4. The instrument features use of 45Hz/55Hz different frequency power supply, fundamentally solving the problem of anti-interference in the field.
5. Fully electronic voltage regulation, the output voltage is continuously adjustable.
6. An internal high-precision SF6 standard capacitor is attached, and this capacitor's tgδ does not change with temperature, humidity, etc.
7. The unique self-excitation method is used to measure fully sealed CVTs, and it can directly test the dielectric loss of C1 and C2.
8. A large screen (240×128) menu-style operation, with a brand-new Chinese interface, is very convenient to use.
9. Multiple protections are provided, and the instrument can quickly cut off the high voltage in cases of high-voltage short circuit, breakdown, overvoltage, overcurrent, and voltage fluctuations.
