Detailed Product Introduction
GYSB Series AC Cascade Test Transformer
I. AC Cascade Test Transformer Product Overview
AC Cascade Test Transformer is a new type of high-voltage testing equipment, this series adopts a single-frame core structure, with the primary winding and high-voltage winding coaxially wound on the core, thereby reducing leakage flux and increasing coupling between windings. The overall structure is compact, with strong versatility, easy to use and carry, suitable for power systems and power users to test the insulation performance of various high-voltage electrical equipment on site. It is an essential test instrument for power equipment testing and preventive tests.
AC Cascade Test Transformer can not only be used for AC power frequency withstand voltage tests, but if equipped with capacitors, silicon stacks, and high-voltage DC microammeters of the same voltage level and capacity, it can be assembled into a DC high-voltage test device to measure high-voltage DC leakage current.

II. AC Cascade Test Transformer Operation Steps
1. Connect the leads according to the wiring schematic diagram, and reliably ground the transformer and control box;
2. Before the test, check whether the wiring at each part is in good contact, and check whether the voltage regulator of the control box is adjusted to the "zero" position;
3. Connect the power supply, the green indicator light turns on, press the start button, the red indicator light turns on, indicating that the transformer is energized, waiting for voltage boosting;
4. Rotate the voltage regulator handle clockwise at a uniform speed to boost the voltage, and closely monitor the instrument indications and the condition of the test object;
5. After the test is completed, quickly reduce the voltage to zero, press the stop button, then cut off the power supply, and disconnect the test leads.
