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 uses AC 220V (380V for above 10KVA) voltage connected to the power control box (console). Through the auto-transformer (external for above 50KVA) inside the power control box (console), the voltage is adjusted from 0~200V (0~400V for above 10KVA) to the primary winding of the test transformer. According to the principle of electromagnetic induction, the required high voltage for testing can be obtained on the high-voltage winding of the test transformer.
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 scenarios;
● Touch-button operation, all functions can be set via buttons, improving product safety and reliability;
● Fully digital calibration method, abandoning outdated potentiometer adjustments, extremely convenient for field use, and accuracy is easy to control (this function is password-protected);
● Button direct setting of test transformer ratio (this function is password-protected), flexible and convenient when connecting testers of different voltage levels, truly achieving one control box compatible with multiple transformers;
