Power Frequency Withstand Voltage Test Instrument:
1. The series high-voltage test transformer is a single-phase transformer with connection group label II. The working process of a single high-voltage test transformer is to connect AC 220V (380V for above 10KVA) voltage to the power control box (console), adjust 0~200V (0~400V for above 10KVA) voltage to the primary winding of the test transformer through the auto-transformer (external for above 50KVA) inside the power control box (console). According to the principle of electromagnetic induction, the high-voltage winding of the test transformer can obtain the high voltage required for the test.
Product Features:
● Voltage, current, time, status information and prompt information data readings are clear and intuitive;
● Full Chinese interface, simple and clear operation, adaptable to various application occasions;
● Touch key operation, all functions can be set through keys, improving product safety and reliability;
● Fully digital calibration method, abandoning the outdated potentiometer adjustment, extremely convenient for field use, and accuracy is easy to control (this function is password protected);
● Keys directly set the transformation ratio of the test transformer (this function is password protected), flexible and convenient when connecting testers of different voltage levels, truly achieving one control box can be matched with multiple transformers;
