Test transformer, power frequency withstand voltage test device, AC withstand voltage test device, power frequency withstand voltage tester, power frequency withstand voltage instrument, power frequency withstand voltage machine.
Product Features:
● Voltage, current, time, status information, and prompt information data readings are clear and intuitive;
●3KVA50KV Power Frequency Withstand Voltage Test Device / Manufactured in Sichuan, full Chinese interface, simple and clear operation, adaptable to various application occasions;
● Light-touch key operation, all functions can be set via keys, improving product safety and reliability;
● Fully digital calibration method, abandoning outdated potentiometer adjustments, extremely convenient for on-site use, with easy precision control (this function is password protected);
● Keys directly set the test transformer ratio (this function is password protected), allowing flexible application when connecting testers of different voltage levels, truly achieving one control box that can be paired with multiple transformers;
● Status reminder function, full Chinese guided operation, can be skillfully operated even without the manual;
● During the test, a flashing high-voltage symbol is displayed on the screen, constantly reminding operators to pay attention to safety;
● Test result display function, can automatically judge test results (test passed or failed), and reliably record the voltage at overcurrent, flashover, or breakdown of the test object;
● Test result audible alarm function, when the test passes or fails, the device emits different alarm sounds, allowing test personnel to directly identify the test result by the alarm sound;
● Pause function, in automatic control, this function can pause voltage rise or fall at any point, with pause time flexibly controlled by the test personnel, convenient for observing the test object's status;
● Automatic timing function. In automatic control, when the voltage automatically rises to the set value, the device automatically starts timing; when the timing ends, the test result is displayed, and the device automatically returns to zero;
● Manual timing function, in manual control, the timer can be started manually; when the withstand voltage time is reached, the device automatically returns to zero (only desktop devices have this function);
● Manual control mode, this mode is similar to traditional electric raise/lower method, with raise/lower controlled by buttons, the device automatically judges upper/lower limits, and has overvoltage protection;
● Intelligent control of voltage rise speed, when the voltage reaches 80% of the target voltage, the rise speed automatically slows down; when it reaches 90% of the target voltage, the rise speed further slows down
