Features Oil type, Dry type or SF6 type testing transformers can be selected as HV unit. 320??240 LCD screen, with high speed thermal printer. Automatic or manual mode can be selected, simple and easy operation. HV voltage/current, LV voltage/current, timing and results are directly displayed on the screen. Over-voltage, over-current protection. Output voltage, HV current upper-limit, LV current upper-limit and timing can be set. During automatic testing, voltage increase and decrease can be paused at any time, more convenient to monitor the test object. Zero start protection. The test could be proceed when voltage is back to zero. Automatic timing when the setting voltage reaches. After timing, the voltage is back to zero automatically. Voltage output is cut off automatically and alarm when the HV/LV current is over setting value. During testing process, press Exit button to quit any tests. Press Emergency button if any abnormal happened. Anti-interference design, able to work in the harsh electromagnetic environment. AC or AC/DC test is selected by customer.
