Variable Frequency Withstand AC Series Resonance Test Resonant Test System

I. Application
DWXZ series resonance test set is widely used for power industry, metallurgical industry, petrochemical industry, etc. It's applied to handover and preventive test of large-capacity&high-voltage capacitive test sample.II. Feature
DWXZ series resonance test set is composed of frequency controller, exciting transformer, HV reactor, HV bleeder, etc. There are two types of frequency controller: console (no less than 20KW) and portable box (less than 20KW). It's made up of controller and filter. The variable frequency series resonance test set is applied to transformer, power cable, GIS, AC voltage withstand test of genset, power frequency withstand voltage test and induced voltage withstand test of transformer and CVT.
1)High stability and reliability.
2)Powerful self-tuning function
3)Support various test mode: self-tuning&manual voltage regulation, self-tuning&automatic voltage regulation, manual tuning&manual voltage regulation, etc. Self-tuning&manual voltage regulation is recommended.
4)Friendly human-computer interaction interface. Test parameter setting, test control, test result, etc. are intuitively and clearly displayed on screen. It has functions of self-clocking, operation prompt, data storage and data query.
5)Perfect protections: zero protection(when voltage output control knob is at zero, system start is forbidden), overvoltage protection, overcurrent protection, arc protection, etc.III.Technical parameter
