Overview
The Variable Frequency Series AC Resonant Test System is mainly designed and manufactured for the AC withstand voltage test of 22kV/600MW power transformer and power system. Adopting multiple separate designs, it can meet the requirements of high voltage and small current equipment test conditions. It is the ideal voltage resistance equipment for the high-voltage test departments and power installation and repair engineering units. The variable frequency series ac resonant test system is mainly composed of a frequency control power supply, excitation transformer, high voltage reactor and capacitor divider.
Characteristic
Our variable frequency series AC resonant test system offers superior quality and competitive pricing, making it highly marketable. The tester is internally controlled by an embedded touch screen, with optimized operation functions for ease of use. Users simply need to set the test program, and the system will automatically complete the entire test process according to the configured parameters. Additionally, its software has undergone rigorous simulation testing to ensure safety, stability, and reliability.
