DTZY series of three phase AC high-voltage test sets are designed to test the AC insulation properties of many types of electrical products such as transformer, cable, electrical machine, electrical part, insulating material, etc.

Features
Program-controlled HV regulating.
Auto/Manual operating mode.
Voltage, Current, Time can be set freely.
Auto step-by-step Regulating when near Goal HV.
Refuse to up HV when reach the customized Max. HV.
Auto Timing at Goal HV, when Time up, Auto Return to Zero.
Auto cut off HV when over the preset Goal HV or HV-side Current or LV-side Current, and then Auto Return to Bottom, and give sound-light alarm.
Auto Capture Peak Voltage when break down.
Test data can be Printed, Auto/Manual Print mode.
Zero start high voltage safety interlock.
External safety interlock for door control or infrared detector.
Emergency-stop push-button for accident.
Optional RS-232/485 port to Computer.
