Product Details

Product Introduction:

Designed according to the new national industry test standards, this test equipment is safe, reliable, powerful, easy to use, and simple to maintain. It is mainly used for insulation strength tests at specified voltages on various electrical products, electrical components, and insulating materials, to assess the insulation level of products, discover insulation defects in test objects, and measure overvoltage capability. It is a product required by power operation departments, electrical appliance manufacturing enterprises, metallurgy, coal mines, electrified railway departments, research institutions, and universities for withstand voltage testing.

Product Overview:

● Voltage, current, time, status information, and prompt messages are clearly and intuitively displayed;

● Full Chinese interface, simple and clear operation, adaptable to various application scenarios;

● Touch key operation, all functions can be set via keys, enhancing product safety and reliability;

● Fully digital calibration method, eliminating outdated potentiometer adjustments, extremely convenient for on-site use, with easy precision control (this function is password protected);

● Direct key setting of test transformer ratio (this function is password protected), allowing flexible application when connecting testers of different voltage levels, truly enabling one control box to be compatible with multiple transformers;

● Status reminder function, full Chinese guided operation, can be skillfully operated even without a manual;

● During the test, a flashing high-voltage symbol is displayed on the screen to constantly remind operators to pay attention to safety;

● Test result display function, automatically judges test results (pass or fail), and reliably records the voltage at overcurrent, flashover, or breakdown of the test object;

● Audible alarm for test results, different alarm sounds for pass or fail, allowing test personnel to identify the result by sound;

● Pause function, in automatic control mode, allows pausing voltage rise or fall at any point, with pause duration flexibly controlled by the test personnel for convenient observation of the test object; 

● Automatic timing function. In automatic control, when the voltage automatically rises to the set value, the device automatically starts timing. When the time is up, the test result is displayed and the device automatically returns to zero;

● Manual timing function, in manual control, the timer can be started manually, and when the withstand voltage time is reached, the device automatically returns to zero (only available on desktop models);

● Manual control mode, similar to traditional electric raise/lower method, with rise/fall controlled by buttons, automatic upper/lower limit detection, and overvoltage protection; 

● Intelligent voltage rise speed control, when the voltage reaches 80% of the target voltage, the rise speed automatically slows down, and when it reaches 90%, the speed further slows down;

● Combines hardware and software anti-interference technology, stable performance, and strong anti-interference capability.
