LYJJ-II Type Insulating Oil Dielectric Strength Detecting Instrument
Main Functions & Advantages:
● Uses microprocessor to automatically accomplish works of boosting, remaining, stirring, standstill, calculating, and printing, carries through the dielectric strength test for the oil under voltage from 0 to 80KV.
● Large scree liquid crystal displayed in English.
● It is easy to operate. It can accomplish the dielectric strength test for 1 cup of oil as per the user’s simple preset. And 1 to 6 times of breakdown voltage value and circling times shall be stored and its thermal printer shall print the breakdown voltage value per time and also its average value after the test.
● It is with the function of power down remaining, and can store 100 of test results. And it can also display the actual environmental temperature and humidity.
● It can boost the voltage at a constant speed, and its voltage frequency corrects to 50Hz, thus to ensure the test to be controlled easily.
● With the functions of over-voltage, over-current, and limiting to safeguard users.
● With the functions of testing temperature display and system clock display.
● It is equipped with standard RS232 connector to set up communication with a computer.
